My chickens have started molting. One of them started molting earlier then the others. The other ones who aren't molting as much yet are picking on her and not letting her get to the food and water. I tried putting out separate food and water, but they won't let her near that, either. What can I do to make sure she gets the proper nourishment? She won't go out to free range, either. She just stays in the coop and sits on the roost. Is this normal behavior for molting? Or is something else wrong?
