Birds that looked fine last night and are dead this morning point to heat, air, feed or infection, and each one leaves a different trail.

Last evening the house was quiet and the birds were eating well. This morning there are four of them lying by the drinkers, and the rest are standing around as if nothing happened. That is the picture that makes a broiler farmer's stomach drop, because the birds that die suddenly are often the ones that looked best.
Sudden death is not one disease. It is a pattern: healthy-looking birds, sometimes the biggest in the house, found dead with little sign of a struggle. Several things can produce that pattern, and some of them are of our own making. The job is to work out which one you are dealing with before the next morning brings more.
Birds that die suddenly are often found on their backs, or on their sides with the legs stretched out. Some have their wings held away from the body, as if they were trying to get air. Many still have feed in the crop, which tells you they were eating shortly before. There may be no blood, no fight marks and no real loss of weight.
Compare that with birds that have been ill for days. A sick bird is thin, sits apart, has ruffled feathers and runs a fever. It is found hunched in a corner, often after a visit to the drinker that did not go well. Sudden death is quicker and less dramatic, and the bird you find is usually in good flesh.
Write down the age, the house, the time of day and the position of each bird. Deaths clustered near one drinker, at the same hour each afternoon, or in one corner point you to a place to look. Deaths scattered across the whole house point somewhere else.
The Ross 308 and Cobb 500 are among the most efficient birds you can buy. They turn feed into weight quickly, and that efficiency is also why they are less forgiving. A heart and lungs have to keep up with a body that is growing very fast, and by the third or fourth week they are working hard. Any extra demand, whether from heat, cold, poor air or a sudden change of feed, can push a bird over.
Some sudden deaths in heavy broilers are linked to the heart and circulation. In the trade you will hear about sudden death syndrome, and about ascites, where fluid builds up in the belly or around the heart. Both tend to show up in fast-growing, heavy birds, and both get worse when the air is poor or the nights turn cold. A bird with a swollen, fluid-filled belly is often short of breath before it dies. You may notice it sitting apart with its head low.
The lesson is not to stop raising fast birds. It is to manage them as the fast birds they are. Check their growth with a day-seven weight check, keep the feed programme steady, and give them air and space in proportion to their weight.
Kasoa afternoons can be hot and close, and a house with the curtains down and too many birds in it will heat up fast. Birds in heat hold their wings away from the body, pant with their beaks open and crowd into whatever shade they can find. Heat deaths tend to come in the hottest part of the afternoon, and they are often the heaviest birds at the back of the house, the ones that have been eating the most.
Harmattan brings the opposite problem. Cold, dry nights, dusty air and houses closed up to keep the warmth in can leave birds short of oxygen, with wet, ammonia-laden litter underfoot. Birds that pile together to keep warm can smother each other, and the ones at the bottom suffer most. A sudden cold night after a warm day is one of the most common ways we see a flock struggle.
Walk the house at night and again early in the morning. Feel the air at bird height, not at your own. Look for birds piled in a corner, a curtain that has blown loose and a fan that has stopped. Check the temperature and humidity if you have a gauge. Ventilation is not a luxury in a house full of birds breathing out at once.
Not every sudden death is a management problem. Some are infections, and a few can move through a house in a day or two. On farms like ours, the usual suspects are gut and blood infections caused by E. coli, which often take hold after a stressful spell. Viral diseases of young birds also matter. Gumboro damages the bursa and leaves birds weak and depressed, and it can cause heavy losses in a flock that is not well protected. Newcastle disease causes nervous signs such as twisted necks, staggering and drooping wings, and it can kill quickly in birds that are not protected.
Every batch we hatch is vaccinated, and we tell you what was given. Typical vaccines in our batches include Marek's, Newcastle, Gumboro and fowl pox. Vaccination is not a guarantee. It depends on timing, handling, the cold chain and each bird's own response, and it does not replace good sanitation. Keep your vaccine records with your death book, and ask your vet how the schedule fits your house.
Sudden deaths often follow a change. A new feed bag from a different batch, an early switch to the finisher, a bag that has picked up damp in the store, or a drinker line that ran dry for an afternoon can each be enough. A bird that gorges on new feed, or drinks heavily after a dry spell, can be the first to collapse.
Check the water first, because it is the cheapest thing to check and the easiest to get wrong. Are all the drinkers working? Are they clean and at the right height for the birds' age? Is the tank filling at night? A bird that cannot drink for a few hours in the heat is at real risk, whether the house is well run or not.
On feed, keep to the phase programme and avoid sudden swaps. Our guide to phased feeding explains what each bag is for. Store feed off the floor and away from damp walls, and throw away anything that smells musty or shows mould. A spoiled bag can make birds ill with no obvious sign until the deaths begin.
Use the table to match what you see with the most likely area to check. Treat it as a set of starting points for a conversation with your vet, not as a diagnosis.
| What you see | Likely area | First checks |
|---|---|---|
| Deaths on hot afternoons, wings held out, crowding at the back | Heat and ventilation | Curtains, fans, stocking density, shade and drinker flow |
| Birds piled in a corner, deaths at night or early morning | Cold, draughts or smothering | Draughts, night temperature, litter depth, heating |
| Heavy birds dying from the third or fourth week with a swollen belly | Fast growth and circulation | Growth against target, feed phase timing, air quality, cold nights |
| Watery, bloody or unusual droppings, with deaths in young birds | Gut or viral infection | Vaccine records, litter, drinkers, a post-mortem and a vet visit |
| Twisted necks, staggering, drooping wings | Nervous-system disease such as Newcastle | Call the vet immediately and limit movement between houses |
| Deaths after a feed or water change | Intake and feed quality | The bag in use, how it was stored, water flow, and when the change happened |
Good management in Ghana usually keeps mortality around 3 to 5 percent, and poor management can push it to 10 to 20 percent. Those are wide ranges, and sudden death is one of the ways a flock slides from the first to the second. Work it through on 1,000 broilers. At 4 percent you lose 40 birds. At 12 percent you lose 120. The 80-bird gap is roughly GH₵1,600 in chicks at the from-price of GH₵20 each, and that is before the feed those birds ate.
These are illustrations, not a forecast. Check today's chick price with us before you plan around it. The point is that a week of hesitation costs more than a day of checking.
Start with the dead birds. Remove them with gloves, examine one fresh bird as our post-mortem guide describes, and write the findings down. Then walk the house. Check the drinkers, fans, curtains and litter, and move crowded birds out of the corner where you can.
Do not panic-change the feed or add things to the water without advice. Many well-meant changes make the picture harder to read. If deaths continue, or if you see any nervous signs, call the district veterinary office the same day. Tell them the age of the birds, the number dead, when the deaths started and what changed in the last week.
Keep the rest of the flock calm. Stress is a trigger in its own right, and quiet handling, fewer visitors and a steady routine help more than most people expect. Our night checks guide shows how to walk the house without disturbing the birds.
No. Heat, cold, smothering, poor air and water interruptions can all kill birds quickly with no infection at all. An infection is one possibility among several, which is why the pattern and the post-mortem matter.
Heavy, fast-growing birds carry more demand on the heart and lungs. When conditions turn hot, cold or poorly ventilated, they have the least spare capacity, so the strongest-looking birds can be the first to go.
Yes. Vaccination reduces the risk from specific diseases but does not cover every cause. Management problems and non-infectious deaths can still happen in a fully vaccinated flock.
Not on your own. Check what changed first, and talk to your vet or feed supplier before you alter the programme. Sudden changes can make the problem worse.
No. Do not eat it, and do not sell it. A bird that died without a clear cause should be disposed of properly, and your vet can advise on whether any birds from the flock are safe to sell.
Most sudden-death losses are easier to prevent than to explain afterwards. Keep your daily checks, weigh a sample early with the day-seven weight check, and follow the feed plan in our guide to broiler feed phases. When a bird dies without warning, our simple post-mortem checks show what to write down before you call the vet.
When you are ready for the next batch of broiler day-old chicks, send the order form on our site or call 024 915 1503. An order starts with a message, not with money. We confirm the price, hatch date and delivery cost before you pay, and chicks dead on arrival are replaced free in the next hatch. The current price list is on our price page.
Written by the Halaal Farms Ghana team. We hatch and import day-old chicks at Opeikuma, Kasoa, and deliver to all 16 regions. This article is general guidance for farmers. For diagnosis and treatment of sick birds, speak to a vet or your district veterinary office.
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.
