We have 4 pullets, 19 weeks old. The golden buff (type of red sex-link) started laying 3 days ago and is now pecking 2 of the others, the #1 and #4 chickens, and pulling out feathers! She does not bother #3, but that one is a buckeye and does not put up with it. Is the new layer trying to buck the pecking order because she did this great thing first? Is it hormones? She is the nosey alarmist of the group. I know #4, cuckoo marans, has zero ambition and is a bit slow. But both she and the #1 (Australorp) are way bigger, so I can’t believe they tolerate it. Help!
