Hi there! We are starting our flock and are just picking up all of the finer points of the care for the girls. I have taken a few classes, etc. and so far the hens are doing really well. However, as it is beginning to get cold here in Colorado, I am thinking a lot about heated waterers. I'm finding it rather silly to buy a 50.00 heater base for my waterer, and I am wondering if anyone has ever used a regular heating pad for the water inside the coop. Thanks.
