I have a flock of 5 hens, Golden Laced Wyandottes, and theyre just approaching one year old. Before the weather here turned bitter cold (like 6 degrees with wind chill in the negatives) about a week or so ago, my "alpha" hen- Bumble Bea- started getting a pale comb. Its not purple or blue as Ive read about.. It started turning peachy, like it was before she was mature, and now its getting grey spots? Kind of shriveled, as in not as big as the other girls' combs. Everyone else's combs in the flock look just fine. After the weather turned bitter cold, she also- like overnight- dropped 90% of the feathers on the back of her neck and head. She isnt bald though, has approx. one inch long pin feathers everywhere she has loss and i can already see baby feathers unfolding at the base of her neck. Not sure whether these two things are related but im getting concerned.. Shes starting to look like a mangy turkey and a couple of weeks ago she was my biggest, fullest feathered hen. She still eats, drinks, and acts completely normal.. Maybe a little more head shaking/feather adjusting. Im completely at a loss and very concerned. Any help would be greatly appreciated!
