Can you post pictures? She may be resting her keel on the roost, or laying in bedding rather than roosting, which is rubbing and putting pressure on that area, causing feather loss and irritation. Check the bottoms of her feet for any signs of bumblefoot, black spots or scabs, that can sometimes cause them to rest on the roost that way. Pictures of anything you find would be helpful.
