My single combed roosters get frostbite every year. One of them used to have 7 teeth on his comb but now only has the middle one remaining. Another ended up with a perfectly smooth comb from all of the teeth falling off because of frostbite. I just raised some new roosters from this spring and I don't want them getting forstbitten too, so are there any preventions? My rooster Tom Jr. already has black spots from this year and we are just beginning the winter season. I did some research and found vaseline, but there are mixed opinions and many people say it really doesn't do anything. I'm almost ready to start sewing them hats! So, does anyone know of a good prevention stradegy? I can't insulate the coop at this time, so thats out of the question. Thanks!
