I had a fox attack 3 weeks ago and understandably my layer has stopped laying but I noticed her comb is not as red and looks a bit dry. She is going to the nest every day and singing the egg song but nothing is coming out. In every other way she seems ok though. Ie eating, dust bathing, scratching etc. she is about 6 months old. Any ideas what's going on with her? She has a few feathers sticking out is she moulting?
