I have 2 Buff Orps and 2 Australorps (chicks, 2 weeks old). Everything I have read says they are docile breeds. They were fine for the first week but then one of the Aussies became very aggressive, especially to the Orps. Constantly pecking at eyes and vents to the point they bleed. I have separated them with a screen. Will they be able to get along in the coop? Any help would be appreciated!
