First of all, this is my first time posting something other than a picture, so I'll be rightfully embarrassed if I've posted in the wrong spot on BYC. I've grown up having chickens, but just as an aide to my father and I haven't been able to reach him regarding my question. I've noticed my New Hampshire Red rooster's comb darkening at the tips. It hasn't been cold enough at all for frost bite (Georgia resident), and he doesn't act sick in any other way. He eats, mates, and struts around like his normal cocky self! I haven't been able to study his droppings specifically, but haven't noticed anything abnormal in the dropping box under the coop either. I'm worried simply because all I have read about blackening combs have been negative and I have taken a particular liking to the big 'ol brute! He's less than a year old, around 7 months old. Thanks in advanced!
