About 6 months ago our rooster (who is no longer with us) was just brutalizing the chickens. When he covered them he would just rake his claws over their backs and pull all the feathers out.. So I have about 5 chickens that are 'bald' from about mid back to the tail. They've made it through the winter and we thought, ok, now it's spring they will get feathers. Well then we had a feather puller, she has been given away. It is now July, while some are moulting and look horrible others show no sign of any feather growth. Is it possible that the rooster damaged the follicle and they will never get feathers? All the chickens we raised from this batch are some of the worst chickens we've ever had...maybe we just got a bad batch.... anyone have any ideas on how to get these girls feathered out? We've checked for mites, they have a special set up for dusting, get oyster shells, hen scratch and layer, eat scraps, they are probably some of the most spoiled chickens I know.......
