Moving Live Birds Without Losses: Crates, Loading and Heat Stress

A batch of broilers is ready on a Tuesday. The buyer's pickup arrives at one in the afternoon, the birds are caught in the heat, packed tight into crates because the vehicle has room for only so many, and the canopy is closed to keep the dust off. Two hours later the crates come off at the market and eleven birds are dead, another dozen are gasping, and the buyer takes the price down for the whole load.

Those losses are counted twice. The dead birds ate feed for six weeks and will never be sold. The stressed survivors bruise easily, lose weight on the journey and dress out badly at the processor. Nothing else on a poultry farm turns a healthy flock into waste as fast as a bad journey, and nothing else is as easy to fix.

This guide covers why birds die in transit, how a crate is designed to keep them alive, how many to load on a given day, when to catch and how to load, what the vehicle must and must not be, how to plan the journey, what to do at the other end, and why washing the crates afterwards is a disease control step rather than housekeeping. It ends with the same thinking applied to hatching eggs and day-old chicks.

Why Birds Die in Transit

A chicken cannot sweat. It sheds heat by panting, which works only if the air around it is cooler than its body and is moving. Put too many birds in a crate, stack the crates in a solid block and park the vehicle in the sun, and the air between the birds stops moving and warms toward body temperature. Panting then does nothing, the birds' core temperature climbs, and they die of heat stress in an hour or two with no mark on them.

Crushing is the second killer. Birds in an overloaded crate cannot all sit, so they climb on one another, and the birds underneath suffocate. A crate that is cracked, or a stack that slides during braking, does the same thing suddenly. Injury is the third: a bird caught by one leg or a wing, swung into a crate door, or thrown onto a pile arrives with a dislocated hip, a broken wing or bruising that a processor will trim off and a live buyer will reject.

Behind all three is a fourth cause that shows up only in the count: birds that were already weak, lame or sick when they were loaded. A journey is a stress test, and it fails the birds that were marginal. Do not load a bird you would not have kept for another week.

Crate Design: Why Ventilation Is the Whole Point

A poultry transport crate is a moulded plastic box with slotted sides, a slotted floor, a top hatch for loading and often a side door for unloading. Every one of those features is about air. The slots let air pass through the crate from any side. The height is low enough that birds cannot stand fully and pile up, but high enough for them to sit with their heads up. Moulded feet lock into the crate below so a stack cannot slide, and they hold each crate a little above the one beneath so air moves between the layers.

Compare that with the alternatives still seen on Kenyan roads: a wooden box with wire mesh, a woven basket, or a gunny sack. Wood and wire splinter and cut, cannot be cleaned properly, hold droppings in every joint, and do not stack safely. A sack has no ventilation at all. A proper crate costs more once and then does the job for years, which is why transportation crates are one of the first pieces of equipment a farm selling live birds should own.

Choose crates for the size of bird you move. A broiler crate and a layer crate differ in height, and a crate for spent hens is not the right one for four-week pullets, which need less headroom and more floor security. Look for smooth inside surfaces, rounded slot edges, a hatch that latches positively and a floor that drains but does not trap toes.

How Many Birds per Crate

The number moulded on the crate is a ceiling, not a target. What actually decides the safe load is floor space per bird, and floor space is used up faster by heavier birds and on hotter days. A crate that carries a certain number of small birds on a cool morning cannot carry the same number of heavy birds at midday.

Use two adjustments. First, by weight: weigh a sample of birds before loading, and as the average weight climbs, drop the number per crate so that the total weight in each crate stays sensible and every bird can sit on the floor at once. Second, by temperature: on a hot day, or for a journey that will end in the afternoon heat, drop the number again, because each bird needs more air moving past it to shed heat.

The test that works on any farm is simple. Load a crate, close the hatch, wait a minute and look through the slots. Every bird should be sitting on the floor with its head up and room to pant. If any bird is on top of another, the crate has too many birds in it, whatever the label says.

Before You Load: Feed, Water and Timing

Withdraw feed before catching but keep water available until the last minute. Birds with full crops and guts soil the crates and one another, and at the processor a full gut is a contamination risk when the carcass is opened. Withdrawing feed for some hours before slaughter is standard practice in broiler production; the journey counts toward that time, so set the withdrawal from the expected slaughter time rather than the loading time, and confirm with your processor what they want. Water stays in the house until catching, because a bird that starts a hot journey already dehydrated has nothing left to pant with.

Catch at the coolest time of day, which in most of Kenya means late night or the hours before dawn. Birds are calmer in dim light, the air is cool, and a pre-dawn load arrives before the sun is high. Dim the lights, work quietly, and move the birds in small groups toward the catchers rather than chasing them around the house.

• Catch by both legs or around the body, never by one leg, a wing or the neck. Carry a few birds at a time, and keep the walk to the crate short.
• Load through the hatch, not the door, lowering birds in rather than dropping them, and close the hatch after every crate.
• Use catching frames or hurdles to pen a small group at a time, so birds are not driven the length of the house.
• Keep the catching team small and briefed. Casual hands who grab birds by whatever they can reach cause most of the bruising.

Crates should be at the house door before catching starts, and loaded crates go straight onto the vehicle, not into a pile in the sun.

Stacking, the Vehicle and the Stops

How the crates sit on the vehicle matters as much as how many birds are in them. A solid block of crates, side by side and hatch to hatch, is cool on the outside and an oven in the middle, because the outer crates shield the inner ones from the breeze. Stack in columns with gaps between the columns, so air moving along the vehicle passes through every crate. Turn the crates so their long slotted sides face the direction of travel.

Keep the stacks to the height at which the crate feet still lock, and strap them down. A stack that shifts under braking either falls, crushing the birds in the crates that land underneath, or wedges against its neighbours and closes the air gaps. If rain threatens, a tarpaulin goes over the top of the load only, with the sides left open; a tarpaulin lashed down the sides turns the vehicle into a closed box.

The vehicle must move air through the load. An open pickup, a lorry with slatted sides, or a canopy with its sides and back open all do. A closed car boot, a sealed canopy, an enclosed van with the doors shut and a matatu roof rack with the crates under a tarpaulin do not, and every one of them has killed birds. If the only vehicle available is enclosed, open every window and door that can be opened and shorten the journey.

Plan the route before catching. Leave with the coolest hours ahead of you, know where you would stop if you had to, and try not to stop at all. A moving vehicle ventilates itself; a parked one does not, and a load that was fine on the road starts heating within minutes at a roadside kiosk. If you must stop, park in shade, across the breeze, and keep it short. At the destination, unload before doing anything else, including paperwork.

Unloading, Recovery and the Dead-on-Arrival Count

Unload as gently as the birds were loaded, in shade, starting with the crates that were deepest in the load because they are the hottest. Count the dead-on-arrival birds and write the number down against the date, the time of loading, the birds per crate and the weather. That record is how you learn what your own journeys can tolerate: a rising count on hot afternoons tells you to cut the load or shift the timing, and it settles disputes with buyers about whose fault the losses were.

Birds that will be processed should rest in a shaded, ventilated holding area with water for a short while before slaughter, because a heat-stressed bird bleeds poorly and dresses out with dark, bruised meat. Our guide to setting up a small poultry processing unit covers what happens from that point. Birds arriving at a new farm, such as point-of-lay pullets, should go straight into a prepared house with water already in the drinkers, feed offered after they have drunk, and no mixing with existing stock until a quarantine period has passed.

Cleaning Crates Is a Biosecurity Step

A crate that has been to a market or a processor has been in contact with birds from many farms and with the droppings, feathers and dust they left behind. Bring it back onto your farm unwashed and you have carried whatever they were carrying straight to your house door. Crate traffic is one of the commonest ways disease moves between poultry farms, which is why our guide to farm biosecurity treats vehicles and crates as a risk in their own right.

1. Scrape and rinse off droppings and feathers at a wash point away from the poultry houses, not beside them.
2. Wash with detergent and a brush, into the slots and corners where material lodges. Disinfectant does not work on dirt.
3. Disinfect with a poultry disinfectant at the label rate and give it the label contact time.
4. Dry in the sun, stacked apart so air reaches every surface, and store clean crates off the ground under cover.

Keep your own crates for your own birds where you can, and treat a buyer's crates as dirty until you have washed them yourself. If a buyer's vehicle comes to the farm, keep it at the gate and carry the crates to it rather than letting it drive up to the house.

Moving Hatching Eggs and Chicks

Hatching eggs travel in trays, pointed end down, cushioned so they do not knock together, and out of the sun. The two things that ruin a batch on the road are vibration, which can damage the yolk and the air cell, and temperature swings, which start and stop the embryo's development. A padded box on the seat of the cab beats a tray on a metal load bed every time. Our guide to handling and storing eggs covers the days before and after the journey.

Day-old chicks are moved in ventilated chick boxes, with holes on all sides and a lining that gives them a grip. A chick lives off its absorbed yolk for the first day or two, so a same-day journey does not need feed or water, but it does need warmth without stuffiness: warm enough that the chicks are spread evenly in the box rather than huddled in a corner, and ventilated enough that the box does not steam. The brooder at the other end should be at temperature before the chicks leave the hatchery, as described in our guide to chick brooding equipment.

If you sell live birds, hatching eggs or chicks, ask at any Fuga branch or on WhatsApp 0716 961 018 about crates, chick boxes and trays sized for what you move. A crate that ventilates, a load counted by floor space and a journey that starts before dawn will bring more of your birds to market alive than any other change you can make.
