Work out how many broilers, layers or other birds your poultry house can carry in Ghana: space per bird, kg per square metre, heat adjustments, warning signs.

A house that measures 9 metres by 12 inside the walls has 108 square metres of floor. That floor can carry nearly 1,200 broilers sold at 2 kg in August, fewer than 800 taken to 2.5 kg in the March heat, or roughly 500 brown layers. The building has not changed. The bird, its final weight and the weather have. Stocking density is the figure that ties these together, and an error in either direction costs money. Too many birds and you lose growth, litter quality and lives. Too few and every bird carries a larger share of the building, the labour and the brooding fuel.
Start with a tape measure, not with the number the builder gave you. Measure the length and width inside the walls, in metres, and multiply them. Then subtract anything the birds cannot stand on: the service bay or feed store, a fixed water tank stand, a blocked-off brooding store. What is left is the pen area.
Many farmers think in feet. One square metre is 10.76 square feet, so divide square feet by 10.76 to convert. A house 30 feet by 40 feet is 1,200 square feet, which is about 111 square metres.
Next, look at the floor the birds refuse to use. A strip along one side where the afternoon sun falls, a corner where rain blows in, a patch under a leaking sheet and the wet ring round each drinker are all avoided, so the birds pack more tightly onto the rest. A house with a tenth of its floor wet or sunlit is a house stocked a tenth heavier than you planned. Fix those faults if you can. If you cannot, leave that area out of the sum. The reasons a building ends up with sun or rain on the floor are covered in our guide to poultry house design for Ghana's climate.
The figures below are working allowances for naturally ventilated, open-sided, deep-litter houses in Ghanaian conditions. They are lower than the densities printed in breeder manuals written for closed houses with fans and cooling pads, and they should be. Treat the upper figure in each range as the limit for a narrow, breezy house in the cooler months, and the lower figure as the starting point for hot weather or a house with low eaves.
| Bird and stage | Birds per m² | Square feet per bird |
|---|---|---|
| Broilers sold at about 2 kg | 10 to 11 | about 1.0 |
| Broilers sold at about 2.5 kg | 8 to 9 | 1.2 to 1.3 |
| Broilers sold at 3 kg or more | 6 to 7 | 1.5 to 1.8 |
| Layer pullets, 9 to 18 weeks | 8 to 10 | 1.1 to 1.3 |
| Brown layers in lay, deep litter | 4 to 5 | 2.2 to 2.7 |
| White (light) layers in lay, deep litter | 5 to 6 | 1.8 to 2.2 |
| Sasso, Kuroiler and Noiler grown to 2.5 to 3 kg | 6 to 8 | 1.3 to 1.8 |
| White cockerels grown to about 2 kg | 8 to 10 | 1.1 to 1.3 |
| Guinea fowl, grown, kept confined | 4 to 6 | 1.8 to 2.7 |
| Turkeys, grown | 2 to 3 | 3.6 to 5.4 |
| Quail, adult, on litter | 40 to 50 | about 0.2 |
Dual-purpose birds such as Sasso, Kuroiler and Noiler are active and do better with an outside run, in which case the house figure matters mainly at night. Guinea fowl and turkeys are nervous in tight quarters and pile in corners when frightened, which is one reason their allowances look generous. If you are raising keets, poults or quail for the first time, start at the roomy end of the range.
Cages are a different calculation. A cage house is stocked by the cage, with each hen given the area fixed by the cage maker, and the limit on the building becomes ventilation and manure removal instead of floor. Whether to use cages at all is a separate decision about capital, labour and egg cleanliness.
Birds per square metre hides the thing that matters, which is weight. The heat, moisture and droppings a flock produces follow its total live weight. Ten broilers at 1.5 kg each put 15 kg on a square metre and are comfortable. The same ten birds at 2.8 kg put 28 kg on it and are in trouble, though the head count is unchanged. A flock that looked roomy in week three is at its limit in week six.
For open-sided houses in Ghana, a sensible ceiling is about 20 to 22 kg of live bird per square metre on the day of sale. Drop to about 18 kg in the hottest weeks of the year. Go as high as 24 kg only in a narrow, high-roofed house on a breezy site in the coolest months. The sum is:
Birds to house = pen area (m²) × kg per m² ÷ planned sale weight (kg)
Take the 108 m² house and a ceiling of 22 kg per square metre, which gives 2,376 kg of live bird at sale:
The house is the same and the correct flock differs by 400 birds. This is why the sale weight has to be decided before the chicks are ordered. If your buyers want a 2.5 kg bird and you stock for 2 kg, you will be over the limit for the last ten days, which are the days the birds are heaviest, hottest and most valuable.
The figure above is the number alive at sale. To get the order, allow for losses on the way. If your records show about 4 birds lost in every 100, divide by 0.96. For the 2.5 kg plan, 950 ÷ 0.96 is 990. Broiler day-old chicks from Halaal Farms Ghana come in boxes of 50, so that is 20 boxes, or 1,000 chicks. Chicks that arrive dead are replaced free in the next hatch, so there is no need to add extra boxes to cover the journey.
For layers the sum is simpler because adult weight varies little. Multiply the pen area by 4 or 5 for brown hens. The 108 m² house takes 430 to 540. Remember that the hens will stay for a year or more, through every season, so stock for the worst month and not the best.
Day-old chicks start in a small brooding area and are given more floor in steps. A common pattern is 30 to 40 chicks per square metre inside the brooding area for the first days, about 20 per square metre by two weeks, and the whole pen by about three weeks for broilers, sooner in hot weather. Keeping them close at the start saves heat and keeps them near feed and water.
The usual mistake is not the starting density but failing to expand on time. A broiler chick weighs four to five times its hatch weight by day seven, so a ring that was right on Monday is crowded by the weekend. If chicks are panting with the heat source turned down, if the litter in the ring is damp, or if they cannot all eat at once, they needed more space yesterday. The physical setup, with ring sizes and how to enlarge them, is in how to set up a brooder.
Every bird is a small heater that never switches off. A broiler close to sale weight gives off heat in the order of 10 to 20 watts, so a thousand of them warm the house like several large electric heaters running day and night. In cool weather that heat leaves through the open sides. On a still, humid afternoon above about 32°C it does not, and the birds begin to store heat in their bodies.
Lower density helps in three ways. Less live weight on each square metre means less heat produced there. Wider gaps between birds let air pass at floor level, where they are breathing. And each bird has room to lie apart from its neighbours with its wings lifted, which is how it loses heat from the skin under the wings.
As a working rule, cut the planned density by 10 to 20 per cent for any flock that will be in its heaviest weeks during the hottest part of the year. That is roughly February to April in the south, before the major rains, and March to May in the north. Plan backwards from the sale date: broilers placed in the middle of February are at their heaviest and most exposed in late March. The same 108 m² house that takes 950 birds to 2.5 kg at 22 kg per square metre takes about 780 at 18 kg.
The building matters as well as the calendar. Take another step down if the house is wider than about 10 metres, has eaves at head height, or sits behind a fence wall that blocks the wind. Circulation fans can win some of that back, but only while the power is on. What else to do on a dangerous afternoon is set out in our article on heat stress in broilers.
A pen can have enough floor and still be overcrowded at the feeders and drinkers. If the equipment in the house serves 600 birds, the house holds 600, whatever the tape measure says. As a rough check, a hanging tube feeder with a 40 cm pan serves about 30 to 35 broilers or 25 layers, and every bird should be able to reach feed and water within about three metres. Our guide to choosing poultry feeders shows how to count what you need.
Layers bring two more limits. Allow about one individual nest for every four or five hens, or the eggs will be laid on the floor, and give each hen 15 to 20 cm of perch if you fit perches. Count these before you settle the flock size, not after the birds have arrived.
The birds and the litter report overcrowding well before the mortality sheet does. Look for these, most of them in the final third of a broiler batch or at any time in a layer flock:
One sign alone can have another cause. Wet litter under a leaking drinker is a plumbing fault. Three or four of these together, in a pen where you know the kilograms per square metre are high, need no further diagnosis.
The argument for squeezing in more birds runs like this: the house is already built, chicks are a small part of the total cost, so another four boxes must be nearly pure gain. The flaw is that the extra birds lower the performance of every bird in the pen. Growth slows, more feed is used for each kilogram gained, more birds die or are downgraded for blisters and scratches, and the batch may need extra days to reach weight.
Compare two plans for the same house. The figures are an illustration of the pattern to look for in your own records, not the result of a trial.
| Plan A | Plan B | |
|---|---|---|
| Chicks placed | 1,000 | 1,200 |
| Losses | 4 per cent | 8 per cent |
| Birds sold | 960 | 1,104 |
| Average sale weight | 2.5 kg | 2.2 kg |
| Total live weight sold | 2,400 kg | 2,429 kg |
Plan B sells almost the same weight of chicken as Plan A. To get there it bought 200 more chicks, fed them, vaccinated them and carried the feed eaten by the extra birds that died. If Plan B behaves like this on your farm, the extra boxes lost money. Put your own chick price, feed cost and selling price into the poultry profit calculator for both plans and compare the result.
Under-stocking has a cost too, and it should not be ignored. Rent, wages, security and the loan on the building are the same for 600 birds as for 950, so each bird carries more of them. In brooding, a very small group of chicks in a large house is harder to keep warm. The aim is the highest density at which the birds still perform, and the only way to find it for your house is to keep weights, feed and deaths for each batch and compare them.
Thinning means selling part of the flock early so that the rest have room to grow on. You stock for the lighter weight, sell a quarter to a third of the birds when the pen reaches its kilogram limit, and take the remainder to a heavier weight. In the 108 m² house, 1,150 birds could be placed, about 300 sold at around 2 kg, and the rest finished at 2.7 kg or more without crossing the ceiling.
It suits farms with two kinds of buyer, such as chop bars and roadside grillers who want a lighter bird and households who want a heavy one at Christmas, Easter or Eid. It has risks. Catching disturbs the birds left behind, and buyers' crates and vehicles can bring disease to a flock that still has weeks to go. Catch in the cool of early morning or evening, keep crates and visitors outside the pen, and do the job quickly. Choosing the day and the weight is covered in when to sell broilers.
Work through it in this order: pen area, sale weight, season of the final weeks, kilograms per square metre, birds at sale, expected losses, boxes to order. Then check the feeders, drinkers and, for layer chicks, the nests against that number.
If you would like a second opinion, send the inside measurements of your house and your planned sale weight to Halaal Farms Ghana through the order form, or call 024 915 1503. Advice is free before and after an order, the minimum order is one box of 50, and the price, hatch date and delivery cost are confirmed before you pay.
A floor of 10 by 12 feet is 120 square feet, or about 11 square metres. In an open-sided structure with mesh on both long sides, that carries roughly 100 to 110 broilers sold at about 2 kg, or 85 to 90 taken to 2.5 kg. An ordinary room with windows holds heat and ammonia, so cut those numbers by about a third or open up the walls first.
It is a fair rule for broilers sold at around 2 kg from a narrow, well-ventilated house in the cooler months. One square foot per bird is nearly 11 birds per square metre, which comes to about 22 kg per square metre at that weight. For birds grown to 2.5 kg or more, or for batches finishing in the hot season, allow 1.25 to 1.5 square feet each.
Brown layers on deep litter need about 4 to 5 birds per square metre, so 500 hens need 100 to 125 square metres of pen. A house 9 metres wide would need 11 to 14 metres of pen length, plus room for a store. Nest boxes fixed on the walls and raised off the floor do not reduce the usable area much, but feeders, drinkers and perches must all fit.
Fans move heat away from the birds, so they can let you hold your normal density through the hot months instead of cutting it. They are not a reason to stock above the cool-season figures. A flock stocked for fans is in danger within an hour of a power cut on a hot afternoon, so do not rely on fans unless a working generator stands behind them.
