Most of my "5" hens have bare bellies and have lost many of their feathers there. Is it some sort of mosting process? It's wimter here in Washington State in the Pacific NW. They are spoiled with all the comforts and have lighting from 5 pm till 8 pm in their coop. That helps them feed just before roosting and helps them see where to jump up to sleep. During the day they get to free roam in the garden and rototill to get bugs and protein. Any ideas about their bare bellies? Otherwise, they act fine and we are getting eggs anywhere from 1 to 4 every day. I think some skip a day here and there. Thanks for any ideas.
