I have a rooster that is in with my hens in the coop full time, and he has a frostbitten comb. Im assuming that he was out of the coop one day that it was really cold and he was standing in front of the coop "protecting his ladies" when we werent here to close the coop door. Or it was when he was drinking and got it wet and then it froze. None of my hens have it though. But anyway, i was reading my poultry magazine, and there was an article in there about this, and they suggested that putting vaseline on the comb might help. I also read that when a rooster has a frostbitten comb he is usually infertile for a while. So does anyone know anything about this? Or how long he would be infertile for? I had planned on collecting some eggs to hatch for the local school ag class who are doing a unit on this in a couple months, and if he is infertile that isnt going to work.
