Adding birds, pecking order, and roosters
Introduce new birds slowly, watch bullying, and keep rooster numbers matched to the hen group.
Flock dynamics
Chickens have a pecking order. Sudden mixing causes injury.
- Quarantine new birds before they join
- Introduce across a fence first; add at dusk if you must mix
- Enough feeder and perch space cuts bullying
- Too many roosters: fighting, over-mating, noisy neighbors
Log culls from injury separately from disease deaths so you can see the real problem.
