I replaced the nesting box in the coop today. The new one has a flat roof. Tonight one of the Easter Eggers was standing on the roof, and the other hens were on the roost, which is slightly higher. For some reason both of the Buff Orpingtons started picking on the EEs. (One of the Buff's was a lot more vicious than the other one.) They were pecking her in the face and drawing blood. (Both Buff's have been laying and the EEs have not started yet.) Is this is an example of "I'm alpha, leave my stuff alone!" I only have one nest box, cuz I only have 4 hens. Should I get another nesting box? I didn't know what to do. Remove the bully hen? Remove the injured hen? Let them work it out? I know this is late on a Saturday night, but I hope someone is online that can advise me what to do. Worried Hen Momma.
