My Easter egger chickens are mean to my barred rock and gave it a bald spot on its wing and lower back and it has trouble getting up, I found it today on its side struggling to stand.. I separated them and helped it stand up so it can walk around. Once I help it up it seems fine and it still eats and drinks water. I just got home from work and its dark so I can't really check for any wounds, so i am going to check in the morning. When I put water and food in the area it walked over and it didn't seem to limp or anything. Any clue whats wrong? If it is a visible injury like a wound what could I do for it? Thanks... Also, It seems like the 3 easter eggers pick on the barred rock and the white bantam, yet they leave each other and the rhoad island red alone. Any ideas how i can get them to stop being so mean. The noneastereggers are all nice and friendly. Are there chicken breeds that are known to be mean?
