Thank you all for the input. She has healed up nicely. My roo is spreading his love around to some of the other hens and I think this gave her break enough to heal without any extra care needed. Thanks again for the advice.
I just started raising backyard chickens this spring. I have a laying hen that has feathers missing from the back of her neck and suspect it is from the rooster mating. Any suggestions on how to prevent this or help the hen out?
