I have a 1 1/2 year old black sex link that is having issues. She stopped laying 4 months after she started, seemed to go into a molt, but just hasn't gotten those feathers back really, and still isn't laying. She's missing a patch on her chest, as well as her vent and just a over tail, a few off her neck too. She is the dominant bird in the coop as well, I see other hens peck where she's missing feathers very rarely. She also bleeds from where one of her tail feathers should be. I haven't seen any bugs on her, I use Diatomaceous Earth in the coop and nest boxes, change the bedding often. She hasn't had moldy food, and the waterer gets changed 1-2 times a week. I am at my wits end so to what is happening to her. She doesn't seem to have a discharge from her vent, but I just started treating her as it might be vent gleet. Any suggestions would be awesome! I can get more/better pics too.
