Brian, I`m gonna try and explain what is happening there. The redness on the feet or legs is common in cold or wet weather. No problems there. To check for lice/mites, pick a couple birds off the roost at night and check under their tails and around their vents with a good flashlight. If you see any tiny bugs scurrying for cover, they need louse treatment. I doubt that`s the case. Anyway, what you discribe sounds like a late moult. Some birds moult real fast and seem to get nekkid overnight. Others moult real slow and you can hardly tell it. In any event, the red skin is caused by exposure to the sun or even to just the air and it is not an irritation. When the feathers grow back, the skin will turn white again. I`m sure you would notice if she was broody, which would be another reason for the belly feathers missing. Chances are it`s just a late moult and she will recover on her own. If you live in a cold climate, a little special care may be in order until she is covered again.........Pop
