I have 4 chickens, a barred rock, buff Orpington, and 2 Easter Eggers. I’ve have them since they were chicks since April. I started noticing that once if the Easter eggers Donna seemed like she lost some feathers on her head. Soon we had a snow storm so I brought the chickens into my unfinished basement. I got a closer look at Donna and she seemed light, not very heavy. One day while they were down there my mom head them being very loud. The other Easter Egger Lily was pecking at Donna. So we found out the pecker. So we took out Lily from the others and put her in her own area for a couple days so she couldn’t harm Donna. Soon the weather got better and we put all the chickens back in there coop. It seemed like Lily wasn’t pecking at Donna but she still seems bossy with her and it makes Donna nervous and stressed and she seems like she’s bullied. So we separated Lily again, she is currently in my basement. I don’t know if I should get rid of Lily or what! What should I do!!?
