To cull a chicken means to deliberately remove a chicken from a flock, usually by killing it, because it is sick, weak, aggressive, unproductive, or otherwise not wanted in the group. In everyday poultry terms, “culling” is a softer word for selecting specific birds and then euthanizing them, often on the farm rather than at a slaughterhouse.

Quick Scoop: What does it mean to cull a chicken?

In chicken keeping and poultry farming, culling is the process of selecting certain birds and taking them out of the flock, most commonly by putting them down humanely. Some backyard keepers also use “cull” when they rehome or give away an unwanted rooster, but in most farming contexts it implies killing the bird.

Why chickens get culled

Common reasons include:

  • Sick or injured birds that are suffering or could spread disease.
  • Very old or low‑laying hens that barely produce eggs anymore.
  • Aggressive roosters that attack people or injure hens.
  • Overcrowding, when there are simply too many chickens for the coop space.
  • Disease emergencies (like avian influenza outbreaks) where entire flocks are killed to stop spread.

In the egg industry, huge numbers of male chicks are also culled because they cannot lay eggs and are not bred for meat.

How culling is viewed

For many homesteaders and small farmers, culling is seen as a difficult but sometimes necessary part of responsible flock management, especially to prevent suffering or disease. Animal‑welfare groups, however, often criticize large‑scale or industrial culling (like mass killing of male chicks or depopulating barns during crises) as cruel and push for more humane alternatives.

Key points to remember

  • “Cull” = select and remove specific chickens from the flock.
  • In most farm contexts, it does mean killing those birds, ideally using humane methods.
  • Reasons range from health and welfare to productivity and disease control.
