I have 2 Orpington hens, one is 5 the other one is 6. At one time I had 5 hens but predation and impacted crop killed the others 3 so now I am down to these 2. At one time the older Orpington (a buff, Lilac) was the alpha hen but she was very meek and docile so by the time I was down to 2 hens, nobody was boss. They got along although the younger hen Scarlett was more boisterous and would squawk for hours, and would hog the treats. She was very annoying. The first of the weekI I was sitting outside with them and I noticed an unusual behavior from Lilac. She was being aggressive and pecking the other Orpington. So unlike her. And she was getting feathers too. So every day since then when I clean out the coop there are feathers in the coop and a lot of feathers too and they belong. to Scarlett. Now she is subdued, hardly any squawking. Still eats well. Lilac is quiet too although she always was. This morning when I went to the coop there seemed to be more feathers than I had ever seen! What could be causing this behavior? This picture I am posting is about 2/3 of what it has been. No way to separate them. Not enough room.
