I have 2 Lt Brahmas (Blondie and Dolly), 2 Black Australorps (Mattie and Aida) and 1 EE Bantam (Lucile) that until recently got along just fine. In the last couple of weeks one of my LBs (Dolly) has been chasing and pecking my little Bantam (Lucile). Dolly isn't aggressive to any of the other hens but has literally stomped on poor little Lucile and frequently pecks her behind her head. Today she actually picked Lucile up by the nape of her neck. I'm not sure what would have happened if I hadn't been outside with them. They have been raised together since they were 3-4 weeks old with no problems/aggression. They all started laying about the same time and egg production has been business as usual - they are about 7-8 months old. It appears to be worse when they are eating. Doesn't matter if it is layer mash, treats or scratch. Am I missing something? What do I do to stop the aggression? I don't want to have to get rid of my cute little bantam.
