Can chickens just not be feasible to intergrate at times? We have one pen with 2 birds, BR and SLW and another with 3 birds, RR and 2 EE's. They've been visible to each other for months now, yet are still temperamental towards each other. The main culprits are the RR and SLW, but our BR does it as well. The Wyandotte always goes right after the other birds, always has. The Red was a scrapper and un-afraid from a young age. She was less than 1/2 the size, but still tried standing tall and going toe to toe. I mainly worry about one getting pecked in the eye. The other day, I shoveled the snow away so they could all mingle closer to each other, and the RR and SL went at it(like usual) and our Red drew blood pecking the Wyandotte at her beak base. Nothing bad, but I didn't like to see blood from my girls. The age difference is 2 mos(mid-March vs mid-May).
