One hen was given to me in July with her tail feathers missin leaving her cloaca exposed and looking red and tender. Three months later, there is no sign of her feathers growing back, but I never see her being pecked. He skin is still red and looking raw. A second hen arrived around the same time with a lot of poop sticking to her feathers. I thought that a new free-range diet (with layer pellets) and a smaller flock would cure that, but despite several cleanings she is still that way after 3 months. Finally, there was an attack on several girls that left two alive but with very low affect. There are no signs of external bleeding, only a few feathers are missing. Their eyes are half closed, they do eat and drink. I have not seen them preening, and one in particular looks like she's trying to sit; she does not have the usual hen stance but more of a hawk stance. What should I make of all this? Thanks for any feedback.
