Why Are My Chickens Pecking Each Other's Feathers Out?
Feather picking is a flock-management symptom — boredom, crowding, protein shortage, or one learned bully — and it escalates if ignored, because chickens mob red.
Most likely causes
Crowding and boredom
What points to it: Picking that started in confinement season (winter, a lockdown), victims with bare backs/vents, tension at feeders.
What to do: Space is the medicine: more square footage, more feeders/waterers, and entertainment — hanging cabbage, straw piles to dig, stumps, dust baths. Bored beaks find feathers.
Protein shortage
What points to it: Flock on scratch-heavy or diluted diets; birds EATING the plucked feathers (feathers are protein).
What to do: Back to a real 16-18% feed, treats under 10%, and protein boosts during molt. Feather-eating specifically screams protein.
One learned pecker
What points to it: Same victims, same bald patterns, and eventually you catch her doing it — often a top hen.
What to do: A few days' timeout in a see-but-not-touch crate resets many peckers; pinless peepers are the old-school fallback for incorrigibles.
It's actually parasites or rooster wear
What points to it: Check the losing-feathers guide map — mites and rooster attention mimic picking.
What to do: Night mite check and pattern-reading before blaming flock politics.
Check these first
Watch quietly for 20 minutes at feed time — you'll usually see the dynamics. Audit space (4 sq ft coop / 10 run per bird minimum), count feeder stations, and check victims for open skin.
When it's probably nothing
Pecking-order enforcement — a status peck at the feeder, brief chases — is normal society. Picking is when feathers actually disappear and skin shows.
