I’ve got 10 hens in the coop, the oldest of which are a Hamburg and a Speckled Sussex, together since they hatched 6 yrs ago (others are various ages 2-5 yrs old). Last few months I’ve noticed the Hamburg spending more and more time on her own, both inside the coop and in the run, last to return to the roost and sometimes opting to sleep outside instead. The last few weeks I’ve seen some of the younger girls aggressively pecking her down the order, to the point where she is constantly running and hiding in corners. Anyone familiar with an outcast syndrome like this? And more to the point, anything to do about it other than just let nature take its course?
