I have a bad situation with my little flock of 5. The original group, 3 plymouth rock were happy as could be. They were about a4 months old when I got them. Then I was feeling kind of, oh, this is great and went out and got two 3 month old black/blue austroplops. They never fit in well with the original three and were clearly low on the order. ok, i said, that's the way it goes. but about a month ago I noticed that the one of the austrolops was being pecked to a point of having no feathers on her rear. Then I saw with my own eyes, that her friend, the larger austroplop was pecking her. I have isolated the larger one for a few days in a dog pen near the coop, then the weak one for a few days and now again the big one. She has been in there for about 4 days and even laid an egg today. Now, what do I do??? Some people say get rid of the weak one, some say the strong one, I, on the other hand I am happy to rotate them in and out of isolation. What do you all think? Am I nuts?
