The first seven days can decide how well a broiler flock performs later.
If chicks spend their first days too cold, too hot, thirsty, crowded or unable to find feed, the loss may show up later as poor growth, uneven birds, weak feed conversion or higher mortality.
Brooding is not just about heat. It is about getting temperature, feed, water, air, litter, light and chick behaviour working together from the first hour.
What is brooding?
Brooding is the management of young chicks during the period when they still need help controlling their body temperature and adapting to feed, water and the poultry house.
The brooder must provide:
- the right temperature;
- clean water;
- easy access to feed;
- fresh air without cold draughts;
- dry litter;
- enough floor space; and
- good observation.
Prepare the brooder before the chicks arrive
Do not wait until the chick truck arrives before checking the house.
Before placement:
- clean and disinfect the house;
- clean feeders and drinkers;
- repair leaks and broken equipment;
- control rodents and wild bird entry;
- place clean dry litter;
- set up the heat source;
- check water supply;
- check ventilation;
- test backup power where needed; and
- make sure the brooding area is warm before chicks arrive.
Use a disinfectant approved for poultry housing and follow the product label. Do not depend on brand names as though one product is always best.
Preheat the house properly
The floor and litter need time to warm up.
A warm air reading with a cold floor can still leave chicks uncomfortable because they lose heat through their feet and body contact with the litter.
Preheating time depends on the house, weather, floor type and heating system.
Use the breeder management guide for the exact temperature target for your strain and system.
Do not manage temperature by thermometer alone
The thermometer matters, but the chicks are also telling you whether the environment is comfortable.
Chicks spread evenly: temperature is more likely to be comfortable.
Chicks crowd tightly under heat: they may be cold.
Chicks move far away from the heat source: they may be too hot.
Chicks crowd to one side: check for draughts, uneven heat, bright light or another disturbance.
This is why chick distribution is one of the most useful brooding checks.
Feed should be easy to find from the first hours
New chicks should not have to search for feed.
Provide enough feeding space and make feed easy to see and reach.
Starter feed should be fresh, suitable for broilers and offered in a form the chicks can eat easily.
Do not use one fixed feed quantity for every flock. Intake depends on strain, age, environment and performance target.
Use our Broiler Feeding and Weight Chart as a reference, then compare with your breeder guide and actual flock performance.
Water comes before everything else
Chicks arriving after transport may be thirsty.
Make sure water is:
- clean;
- easy to find;
- available in enough drinkers;
- at a suitable temperature; and
- free from contamination.
Check that small chicks can reach the drinkers without climbing or struggling.
Do not use one universal rule such as flushing water lines a fixed number of times every day. Flush when needed to maintain clean, fresh water and manage water temperature according to the system.
Check crop fill
Crop fill is one of the best early indicators of whether chicks are finding feed and water.
The crop is the small storage pouch at the base of the neck.
When chicks are placed, sample a group at intervals and gently feel the crop.
A chick with a soft, rounded crop has usually found feed and water. A hard crop may suggest mostly feed without enough water. An empty crop means the chick has not found enough of either.
Use the breeder guide for the timing and crop fill targets appropriate to your strain.
Ventilation matters during brooding
Closing the house completely to keep chicks warm can create another problem.
Chicks need fresh air.
Ventilation helps remove:
- moisture;
- carbon dioxide;
- ammonia;
- dust; and
- excess heat.
The goal is fresh air without exposing chicks to cold draughts.
Keep litter dry and comfortable
Start chicks on clean, dry and absorbent litter.
Do not use one fixed litter depth for every farm. The suitable depth depends on material, floor, season and house design.
Watch for:
- wet patches;
- drinkers leaking;
- caking;
- mould;
- strong ammonia smell; and
- dust.
If litter becomes wet, use our Wet Litter Troubleshooting Guide.
Lighting should help chicks find feed and water
Young chicks need enough light to move, eat and drink.
But lighting programmes vary by breeder and production system.
Follow the breeder guide rather than copying one fixed light schedule from another farm.
Give chicks enough usable space
A brooder guard or confined starting area can help chicks stay close to feed, water and heat.
But there is no single circle size that suits every flock.
Space depends on:
- number of chicks;
- heater type;
- feeder and drinker layout;
- house shape;
- weather; and
- how quickly the chicks spread out.
Expand the usable area as chicks grow and as the environment allows.
Check chick quality on arrival
Look for:
- alert chicks;
- clean dry fluff;
- well healed navels;
- straight legs;
- normal activity;
- no obvious dehydration;
- no abnormal breathing; and
- low early mortality.
Poor chick quality can limit performance even when brooding is good.
Daily brooding routine
Every day, check:
- chick distribution;
- temperature;
- water availability;
- feed availability;
- crop fill in the early period;
- litter condition;
- ventilation;
- mortality;
- droppings; and
- unusual sounds or behaviour.
Do not rely on one visit in the morning. Conditions can change during the day and night.
Vaccination during brooding
Vaccination programmes depend on local disease risk, hatchery practice, maternal immunity, vaccine type and veterinary guidance.
Do not copy one universal vaccination schedule from another farm.
Keep good records of:
- vaccine used;
- batch number;
- date;
- method;
- who administered it; and
- any reaction or problem.
What causes high mortality during brooding?
Common causes include:
- temperature problems;
- poor chick quality;
- water failure;
- feed access problems;
- poor ventilation;
- wet litter;
- infection;
- transport stress; and
- management mistakes.
If chicks are already dying, use our High Brooding Mortality Guide to troubleshoot the problem in the right order.
Do not diagnose coccidiosis from diarrhoea alone
Diarrhoea in chicks can have several causes.
Coccidiosis is one possibility, but diagnosis should consider age, droppings, mortality, growth, post mortem findings and farm history.
If coccidiosis is suspected, use our Coccidiosis in Poultry Guide.
Common brooding mistakes
- Heating only the air and forgetting the floor.
- Using one temperature schedule for every strain.
- Waiting until chicks arrive before checking equipment.
- Keeping the house sealed because of fear of cold.
- Providing too few feeders or drinkers.
- Ignoring crop fill.
- Leaving wet litter under drinkers.
- Using fixed feed quantities without checking actual intake.
- Changing several things at once when chicks look uncomfortable.
Brooding checklist before chick placement
- House cleaned and prepared.
- Litter dry.
- Heat source tested.
- Floor warmed.
- Water ready.
- Feed ready.
- Feeders and drinkers positioned correctly.
- Ventilation working.
- Backup power ready where needed.
- Mortality and brooding record sheet ready.
Bottom line
Good brooding is about watching the chicks and correcting problems before they become losses.
Use the breeder guide for exact temperature, lighting, space and performance targets; then use chick behaviour, crop fill, feed intake, water intake and mortality to check whether the system is actually working.
The thermometer gives you a number. The chicks tell you whether that number is working.
