I have a Dominique chicken that is about seven months old. She is the runt of the flock, smaller than the others, but never showed any signs of being weaker than the others. The past week I have noticed her hanging out in the coop more than the others. Her eggs have been paler and smaller than the others and rougher textured, but they have come fairly regularly. I noticed a few days ago that the feathers on her head have changed. The quills are still there but the fluffy feathery part is missing. The problem seems to be spreading onto her neck now. Could she be molting? She isn't even a year yet. I see no evidense of bugs or any strange droppings that would indicate illness. Her eyes seem clear. Any advice would be greatly appreciated.
