I have some roosters that are pastured. So they do get some wind, even though their coop has a roof. Almost all of the single-combed roos exhibit some frost damage on their combs. The problem: my one Barred Rock rooster actually has no comb points left. They just blackened and fell off. My question is: will the comb points regrow? Also, I've heard that roosters have problems with infertility the spring after they've had frostbitten combs. Will roosters with unscathed combs, like Wyandottes, also have this problem? I just saw this. http://www.dummies.com/how-to/content/how-to-treat-frostbite-in-chickens.html Roosters with frostbitten combs may be temporarily infertile. But its not the frostbite that causes the infertility; its the amount of cold that the chicken has been exposed to. Usually fertility is restored after conditions improve and the roosters body recovers from the stress. Is this true? BTW I just looked and, to be sure, the one author is the same as Nifty Chicken. Perhaps I should be careful when asking as to the verity of this? Anyone else have experience on this?
