When to Cull: The Realistic Conversation
By Bertie Holcombe, Poultry Editor — Published 1 March 2026 · Last reviewed 28 March 2026
Every backyard keeper who keeps chickens for more than two years will cull a bird. The keepers who think through this decision before they need to make it handle it better than those who do not.
When culling is the right decision
Chronic respiratory infection: a hen that wheezes, has discharge from nostrils or eyes, or rattles while breathing is likely infected with Mycoplasma gallisepticum or a similar chronic respiratory pathogen. There is no practical treatment at the backyard scale that eliminates these organisms — antibiotics suppress symptoms temporarily, and the bird remains a source of infection for the rest of the flock for life. A hen with a confirmed chronic respiratory infection and a flock of birds you intend to keep long-term is a culling decision, not a treatment decision.
Prolapse: a hen whose vent tissue has prolapsed (turned outward) has a 60% probability of re-prolapsing within 30 days even with perfect management. Re-prolapse typically results in flockmates pecking at the exposed tissue. This condition warrants immediate isolation and honest assessment of prognosis.
End of productive life: a heritage-breed layer remains in fair production through year 3-4 and declines thereafter. A hen in year 6 may lay 20-30 eggs per year. Whether to keep her depends on your values — some keepers maintain hens as pets through old age; others cull non-productive birds. Both choices are defensible.
Humane methods
Cervical dislocation (neck dislocation): the fastest and most commonly used backyard method. Hold the hen by the legs with your non-dominant hand, place the index and middle fingers of your dominant hand behind the skull at the base of the neck, and pull down sharply while pushing the head backward. Done correctly, death is instantaneous. Learning this properly from a video tutorial before you need it is genuinely useful — a poorly executed attempt is the worst outcome for all involved.
A hatchet or killing cone: traditional farm methods. The killing cone restrains the bird in an inverted position; a sharp hatchet or knife severs the spine above the head. Requires a dedicated area and cleanup. Standard method for meat processing.
CO2 euthanasia: a sealed container filled with compressed CO2 from a fire extinguisher or dry ice causes rapid loss of consciousness in 30-60 seconds and death in 3 minutes. Appropriate for ill birds where handling may cause distress or where the keeper is not comfortable with manual methods.
Frequently Asked Questions
Can I eat a hen I culled because she stopped laying?
Yes. A mature laying hen is edible and safe to eat if she was healthy before culling. The meat will be tougher than a young broiler and requires 3-4 hours of low-temperature braising rather than dry-heat cooking. Stewing hens are a traditional ingredient in stock, coq au vin, and slow-cooked dishes.
