Hi, I have a hen I suspect is a bit older, she is at the top of the pecking order, and last week during the snowstorm I went in the coop and noticed her belly is BARE. There is a rough callous I assume from the perch, but it was not bloody or red. She looks shaggier each day, and there are more feathers in the coop, and the other day I noticed a new bald spot on the front of her neck. Her legs have just "frizzy" brown feathers. She is a black orpington and has very few greenish black feathers anymore, like just undercoat feathers?? None of the other hens have missing feathers. I don't see mites, I was able to pick her up, but as a novice I wasnt totally sure what to look for. Otherwise she seems ok, integrated with flock, normal poo I think. She hasn't laid since November??? I thought she already molted in Sept/October with the other ones. PLEASE HELP MARTHA IS ONE OF OUR FAVORITES!!
