My hen Penny has a bare belly probley for a couple weeks but I just noticed how bad it looks today when we picked her up to see why she was limping.... found a callous on her foot pad, I don't know if a small pebble got stuck and a callous formed around it but I picked it off and now she has a small wound so I put some skin adhesive on the area... anyway we got a good look at her belly and the feathers are gone and the belly is very red and very warm. Otherwise she is an excellent layer, 19 months old. The weather is really getting cold so I hope her feathers grow back soon!! Anyone know why she would lose belly feathers, do they ever have a partial moult?? I've heard when they go broody they will pull their own belly feathers out but she hasn't been broody from what I have read about it. Also wouldn't they only go broody in the spring? I carried her into the coop because now her foot could be extra sensitive to the cold ground.
