Is it a common occurance for older hens (about 2 years old) to have bald heads? I think it may be a symptom of molting but wondered if this was a common look to molting hens? I have roosters and I've seen them in action. They do grab at the hen's comb when they are doing their thing but I've noticed that several of my hens are largely bald now where they weren't this summer. They seem healthy and vigorous and eat well and although its really cold now, they do take a walk outside for a little while when its not windy. The coop is not overcrowded but I do have 4 young roosters which I plan to cull down to 2 in a few months that live with 26 layers. They tend to clump together in the coop b/c of the cold and perhaps they are picking at each other a little... I've been giving themcracked corn and protein treats along with their feed right now since they are not laying all that great right now. Would any of these factors contribute to the bald head look?
