been using what to keep the water from freezing???I have been using pine shavings and DE in the coop as a deep litter method. How do the pellets do for maintaining heat? I am not using any heat in the coop and so far they seem fine. We have been using a roof deciding cable to keep the water from freezing, which is also working great (I was skeptical at first, but daily morning checks have proven that it works). The pellets are the same as the wood stove pellets? How convenient is that?
