Not something I would normally think about when it's 90 degrees in Michigan in the summer, but I was at TSC yesterday talking to the guy who knows more about chickens there than anyone else. He said last winter his ISA Brown's combs all froze off and he just kindof shrugged it off. He said they got wet from the waterer and there wasn't anything he could do about it. I've talked to several other chicken owners here and they all just dismiss combs freezing off as normal and to expect it. Yikes! Then I read an old OLD Mother Earth News article that said to not give chickens liquid water if you have cold snowy winters, that they'll get enough water eating snow. Even if I use a water heater, the liquid water will still freeze on their combs. I've had frostbite... it hurts. I'd hate to see their combs all freeze off if there's a simpler way. Comments? Suggestions?
