Hi there, I'm hoping I can get some help asap We have a neighbor who has four rhode island hens and she is done with them and wants to get rid of them. They are about 2 years old and all but one has missing back butt feathers. One she said is brooding and does nothing but lay on fake eggs all day in her nesting box (she put them out there) and she said in the entire time she's been an adult her feathers on her butt are gone completely with just skin and it hasn't grown back. They are not free range, they are living in an enclosure about 10x10 feet wide with their house in it as well. She has never treated them for worms, etc. and they get hen scratch everyday twice a day and that's all, no pellets, etc. Could their feather loss be because of stress and lack of space? Or do you think it might be that they have mites, etc. I am worried about bringing these chickens into our backyard in a brand new coop, etc. if they are infested with stuff but she seemed to just think they are pecking at each other and I'm wondering if that isn't the truth because they are bored but then why is just one perfectly fine looking? Sorry for all the questions, these will be my first chickens and I really want to make sure that we are successful with them from day one.
