Hey, Uzi (and boys), I remember last year when you were so upset over the tiny little bit of frostbite Memnoch achieved, knocking yourself out because you didn't do the ventilation right. I have a number of large combed roos (Light Sussex), and last winter their combs and large wattles took some big hits. None got infected, but I think it really hurt when they tried to stick their heads into the feeders. My thinking about frostbite at the time was that single combed roosters MIGHT get frostbite, but that it could be prevented given the right husbandry. Since then, I've come to believe that single combed roosters WILL get frostbite, no matter what you do, short of heating the coop to above freezing. So i guess you could say I'm sort of resigned to it - but it's a subject of interest to me, and I'll keep researching it. Right now I'm at the point where I believe I should have chosen a breed more suitable for this climate. I love my LS Roos, they are perfect in almost every way; but they suffer from frostbite every winter. (My other single-combed roos seem not so vulnerable) If ever I wanted to show any perfect progeny, I would have to house them in winter-heated shelters, I am sure. I guess one thing I could do is attend some poultry shows and ask the breeders how they keep the combs so pristine. Or get some information from a 4H chicken raiser. I know your heart bleeds for your boys - 'cause mine hurts for mine - and if I find out anything I think useful, I will let you know. Meanwhile, good luck and happy Solstice.
