I have a hen that we got in the spring and she is losing feathers. They have all already molted. This is different, the feathers almost look like they're broke off and there are some bald and red spots. she's also walking kind of wobbly. She is pooping normally and eating. My chickens are locked in a coop at night and free-range all day. I feed them organic layer pellets, cracked corn, and kitchen scraps. I thought it might be lice or mites, but when I went out last night and looked at her I didn't see any of the red mites and I haven't seen any lice either. Now at least one of my other hens is also getting this. I did some research and bought Elector PSP to treat the coop and the hens. Could it be something else or do you think I am on the right track? The spray was very expensive, and if it's not going to resolve the issue, then I would Like to be able to return it, As it was $150 for 8 Oz. I feel very sorry for her, almost to the point of putting her down. I definitely don't want to lose my whole flock. Any help would be appreciated. Thank you in advance. These are pics of my poor girl.
