The broiler batch is grown, weights are good, customers are waiting. But carcasses with torn skin, leftover feathers and dark blotches sell worse, and meat that wasn’t chilled fast spoils within a couple of days. Slaughter is the last step where you can lose what the whole grow-out earned. Below is the order of work and the figures processors rely on.
Preparation
- No feed for 8–12 hours before slaughter, water freely available. An empty gut means clean evisceration without contaminating the carcass.
- Withdrawal period. If the birds were treated, make sure the withdrawal period has passed (on withdrawal periods).
- Calm catching in dim light, without chasing: bruises and broken wings show on the carcass.
- A clean area and tools, plus cold water or a fridge for chilling — set up before you start, not along the way.
Killing
Before bleeding, birds are stunned or killed by a rapid method that doesn’t leave them conscious. In many countries slaughtering for sale requires proven competence — in the EU and the UK, for example, a certificate of competence. Bleeding must be complete: leftover blood causes dark spots and shortens shelf life.
Scalding and plucking
| Method | Water | Time | Result |
|---|---|---|---|
| Soft scald | 51–54 °C (124–130 °F) | up to 2 minutes | Skin stays intact and light; feathers come out harder. For broilers and young turkeys |
| Hard scald | 60–66 °C (140–150 °F) | 15–30 seconds | Feathers come out easily, but the outer skin layer comes off and the carcass darkens faster |
Test with a large wing feather: if it pulls out easily, it’s ready. Overheating “cooks” the skin, and it tears in plucking. Ducks and geese are scalded longer because of their dense feathers and down, and are often finished with wax.
Chilling
EU rules require poultry meat to be chilled to 4 °C or below right after evisceration. A carcass left to cool on the table gives bacteria hours to multiply.
- Ice water — fast; the carcass takes up a little water;
- a fridge or cold air — slower; the carcass is drier and keeps better.
Carcass yield
A broiler’s eviscerated, chilled carcass weighs roughly 70–78% of live weight: closer to the low end with air chilling, the high end with water chilling. In trials, soft scalding gives 1.5–2 points more yield than hard scalding. Calculate yield for every batch: it’s the direct answer to how much meat you sell per kilogram of live weight.
A batch of 200 broilers at 2.6 kg is 520 kg live weight. At 72% yield that’s about 375 kg of carcasses. Just 3 points of yield is 15 kg of meat per batch.
If the meat is for sale
- In the EU, a small producer may sell poultry meat slaughtered on the farm directly to consumers or to local retail without slaughterhouse approval if volumes are small; several countries set the limit at 10,000 birds a year.
- Cutting and packing usually require a food safety system (HACCP principles) and batch records.
- Rules vary a lot between countries: ask your local veterinary or food authority what’s needed before the first batch.
How to find buyers and handle the paperwork is in selling eggs and meat from the farm.
Slaughter in your records
In EggPulse, when a batch is removed you record how many birds were slaughtered, and meat sales go into income. Together with the batch’s feed and costs, that gives the cost per kilogram of carcass — and shows which batch earned more.
