I have a hen who is molting. It's February in Vermont! We do light our coop. She did not molt this fall, but she is only 10 months old so I didn't expect a molt. I did have some late molts this winter but I figured the warm weather was the cause for their confusion. I see no signs for concern but should I be concerned? No one has laid eggs in a long time but we lost 3 hens to Hawks this fall and they were so freaked out.
