A flock that finishes together sells in fewer trips and wastes less feed. Here is how to measure the spread and deal with the tail.

Walk into a healthy broiler house in the fifth week and you can usually tell in a minute whether the flock is even. The birds at the back look about the same size as the birds at the feeder. The litter is dry in most places, and the flock moves as one. Then there is the house where a few birds look like they came from a different hatch, stand apart at the drinkers, and still have bare patches on the wings when the rest are fully feathered.
Those stragglers are the reason this guide exists. A flock that finishes together is easier to feed, easier to catch and easier to sell in one trip. A flock with a long tail keeps the feed bin busy long after the first birds are ready, and buyers usually want birds in a similar size range. Uniformity does not add a single bird to the house. It changes how much of what you spent turns into money.
This guide explains what uniformity means on a Ghana farm, where the spread starts, what widens it, how to check it without a laboratory, and what to do with the tail. The chicks we supply are sorted, counted and boxed in ventilated boxes of 50 before they leave us. The rest of the outcome depends on the brooder and the house, and most of that is in your hands.
A uniform flock is one where most birds reach market weight at about the same time and close to the same size. The usual yardstick is simple to use. Weigh a sample of birds, work out the average, and count how many sit within about 10 per cent above or below it. The more birds inside that band, the more even the flock. A large share well outside the band means something in the house, or in the chicks, needs attention.
Uniformity is not the same as a high average. A flock can average the target weight and still be spread wide, with a heavy group that sells well and a light group that drags. Both groups eat from the same bin. A grower who looks only at the average can miss the tail until it is too late to fix this batch.
On a well-run farm, a broiler reaches market weight in six to seven weeks. By then the spread you see at the catch reflects what happened in the brooder, the first weeks in the house and the middle of the cycle. The last week rarely undoes an early gap, so the work that matters most happens well before the weigh-in you do for the sale.
The spread starts before the chicks reach your house. Our eggs spend 21 days in the incubator at around 37.5°C, and the chicks come out over a window of hours rather than all at once. Chicks that hatch at the edges of that window tend to start a little behind. Our incubators hatch under 5,000 chicks a week, and the sorting and counting happen before the boxes go out. Even so, a box of 50 is never a box of identical birds. Some will always be smaller on day one, and a healthy house can close most of that gap.
The brooder is where the gap either shrinks or sets. Uneven heat, a drinker placed too far from the chicks, or a feeder with too little space in the first days leaves the timid birds behind. A chick that is slow to find feed and water in week one is often the bird still behind at the catch. Those early days carry more weight than their size suggests.
Hatch and brooder problems show up later as a spread you can measure in the house. That is why the fix belongs in the first fortnight, when the birds are small and the brooder is the only thing they know.
Once the birds are on the floor, a handful of things separate the even flock from the uneven one. Most of them come down to access. A bird that cannot reach feed and water the way the others do grows more slowly, and the gap compounds every week.
Heat plays its part too. Birds at the edges of a hot spot eat and drink less, and by the time you see them lagging they have usually been behind for days. The harmattan brings the opposite problem in the cold early mornings, when draughts push birds into the same corners and they huddle instead of feeding.
Feed is more than half of what it costs to raise a broiler, so the money in a spread flock sits mostly in the bin. Our reference figures put a broiler at about 4.2 kg of feed by market weight, and a 50 kg bag broadly costs GH₵400 to GH₵470, depending on brand and season. Those two numbers are enough to work out what a bird's feed costs, and what a bird costs when it stays in the house longer than it should.
The table below uses only those figures. It is a planning tool, not a quote. Prices move, so check the bag price at your feed shop in the week you buy.
| Line | How it is worked out | Illustrative result |
|---|---|---|
| Feed price per kg | A 50 kg bag at GH₵400 to GH₵470, divided by 50 | GH₵8.00 to GH₵9.40 per kg |
| Feed per bird to market | About 4.2 kg per bird, at the per-kg range above | GH₵33.60 to GH₵39.48 |
| Feed per box of 50 birds | The per-bird line above, times 50 | GH₵1,680 to GH₵1,974 |
| Extra feed if all 500 birds eat 0.1 kg more each | 500 times 0.1 kg is 50 kg, which is one bag | GH₵400 to GH₵470 |
The last line is the one to remember. A tenth of a kilo per bird sounds like nothing. Across 500 birds it is one full bag. The table also assumes every bird eats the average amount, which is not quite true, and it leaves out the days a light bird stays in the house after the rest have gone. Those days are the hidden cost of a spread flock, and the extra feed tends to go to the birds still in the house.
You do not need a laboratory to check uniformity. You need a scale that suits the birds, a notebook and half an hour in the house. Our guide on weighing broilers with minimal stress covers the handling side. Here is the short version of how to read the result.
Read our day-seven weight check guide before you need it. A lag that shows at week five is often a gap that started in the first week, and the early check is where you catch it while it is still small.
Say the check shows a light group of birds in one corner. Work through the house in this order before you decide anything about selling:
The tail is not always a fault. Some birds are slower because of where they started, and a few will be slow whatever you do. A tail that keeps appearing in the same corner, batch after batch, is a house problem, and the house is the thing you can change.
When the spread is wide, you have two choices. You can sell the whole flock on one day and accept a mixed lot, or you can split the sale. A split sale means taking the heavier birds first and keeping the rest a few days longer. Many buyers prefer lots where the birds are close in size, so a mixed lot can be harder to price. A split lets you sell the first group without waiting on the rest.
A split has a cost. Every extra day the light birds stay in the house is feed you have already paid for and cannot sell yet. Run the sum first, using the per-bird feed figure from the table, and compare it with what the heavier group fetches in your market. Our guide on selling part of the flock early works through the timing in more detail.
Keep the stragglers fed and watched during a split. Do not let them become the forgotten group. The birds left behind are the ones most likely to show a problem first, so keep the morning count honest to the last bird.
Perfect uniformity is rare, and it is not the goal. The goal is a batch that sells in one or two trips without a long tail of birds you are feeding for nothing. A good batch looks like one flock in the house. Most birds sit close to the average when you weigh a sample. The lightest birds are few, and they are not clustered in one corner. Feed use is steady from week to week, and the morning count holds few surprises.
When a batch falls short of that, do not blame the chick first. Walk the house, look at the corners and at feed and water access, and check the early weeks against your brooding notes. Most of the answers sit in those three places.
No. Uniform means the birds are close in size. A flock can average the target weight and still be widely spread, with heavy birds at one end and light ones at the other. Look at the spread as well as the average.
Our chicks are sorted, counted and boxed in ventilated boxes of 50 before they leave the hatchery. We do not promise a box of identical birds. Some variation is normal, and most of what happens next depends on the brooder and the house.
There is no single figure that fits every house. The usual yardstick is the share within about 10 per cent of the average. Track your own share each week, and if it sits well below the rest of your records, look at the house before you blame the chicks.
Sometimes. Work out the feed for the extra days first, using the per-bird figure, and then compare that with what the heavier group fetches in your market. If the extra feed costs more than the difference in price, sell the whole lot.
A batch that finishes together starts with chicks that arrive on the agreed date and a house ready to receive them. Set up the brooder, the feeder space and the drinker height before the boxes come off the vehicle, and use the day-seven weigh-in to see whether the batch is starting level. Our broiler day-old chicks are the Ross 308 and Cobb 500 we import, and the price page shows the current from-prices. Confirm those figures with us before you budget.
When you are ready, send the order form on our site or call 024 915 1503. You can also email support@halaalfarmsghana.com. Tell us your target sale date as well, so the hatch timing fits your plan. We confirm the price, the hatch date and the delivery cost before any payment, and chicks dead on arrival are replaced free in the next hatch. If you expect to sell in stages, read selling part of the flock early before the birds reach the middle weeks.

A weekly weighing routine for broiler farmers: how to pick an honest sample, the weights to compare against from day 7 to day 42, the average and uniformity sums, and what to do when the flock is behind.
Feed cost per kilo of broiler depends on how much feed each kilo takes and what you pay for it. These ten habits lower both without starving the birds or buying additives.
Heat kills the heaviest broilers in the last days before sale. This guide explains why, shows the signs in order, and sets out the house, stocking, water and feeding changes that prevent it, plus an afternoon emergency plan.
