I need some advice. I have a roughly 4X6 coop made of thick wooden boards sitting directly on the ground (dirt floor base). About a week ago, I added a very deep layer of pine shavings- I won't call it "deep litter method" because I know there is a real science to that, and I'm not an expert in that approach. But, when the weather dipped to single degrees, I started to worry the plain dirt floor was not insulated enough (I don't heat the coop). The dirt was actually still light and fluffy, not frozen like the dirt out in my run- but the poop was frozen on the ground in the mornings. So because I'm a worry wart, I went ahead added these shavings over the top of dirt/peat moss*, and I'm now having second thoughts. I'm not sure if the shavings are going to add too much wetness and humidity to the coop (today is rainy, but snowy days are coming any day now), and will thus put my girls at risk of frostbite. I think ventilation is adequate, but today I was noticing the layer of shavings is no longer easily "fluffed," and it's already starting to look a little tired. We are supposed to have a relatively warm and sunny weekend, so that might be my last real opportunity to strip out all the shavings and go back to a clean dirt floor for the rest of the winter. Any advice? What would you do? *I know many people dislike peat moss as floor material- I have had really good luck with it, no excess dust/respiratory problems, and a real cinch to clean out. I have also tried sand, but had lot of problems with clumping and freezing, so probably wouldn't go in that direction.
