My hen is about 1 1/2 years old. She stopped laying about 4 months ago or longer. She is acting healthy, her comb and wattles are bright red. Her legs are yellower than the rest. I wonder if its just because she isn't laying? She eats, she is a really good weight. But she has a bright red butt. When she lifted her tail to defecate it was bright red and looked dry. She has some yellow patches of skin on her back. But we also feed her a high cracked corn and mineral diet. It's mixed by a grain elevator for us with boosted calcium. However, I'm not sure it is vent gleet because her vent is nice and pink not beat red. We took her out of the main pen to get a break from the rooster. I see tiny feathers growing back. But not very much. I do notice some of her feathers are dull. I thought maybe lice, but no one else is having this issue. Could it be a skin infection? I am in the process right now of making some fermented feed. Should be ready in a few days to give her more probiotics, protein etc. I think it would be good for her overall health. I am just concerned about the bright red butt. I feel so bad. any ideas?
