Hello, I live in central Nebraska where we've had a very fridged and damp December. Most of my chickens have a bit of frostbite on their combs, but my Roosters have it very bad on their combs and wattles and now they are limping and behaving sluggish. I cannot move them out of the coop as I have no where else to keep them. I have fresh bedding in the coop, plenty of ventilation and their food and water is kept outside. They sleep on roosts made by 2x4, on the 4 side. And they have bag balm on all of the frost bitten places. My question is about their feet. The look a bit swollen and red, but definitely not black. I don't see any sores on them. It's been much warmer these past two days, but my roosters seem to be feeling worse, not better. I'm very worried about them, but I don't know what else to do.
