Hi, I know this is an older post, but curious how your chicken healed up or how she’s doing now? I have one that has the same red skin and feather loss on her belly and have no idea what’s it’s from. ThanksI have a 1 yr old rhode island red hen that has lost the feathers on her belly, the skin is red and the feathers look crusty. I checked her and did not see any mites or other bugs. I checked our other girls and it is just her. She acts normal, eats, drinks, perches at night and still laying eggs everyday.
Any idea what it could be?
