Okay this is my 1st winter with chickens, it's not usually this cold here in TN for an extended amount of time. It's 12 degrees F here as I compose this, and it's only supposed to get colder over the next few days(going to be 4 degrees Tuesday morning) and remain really cold for the next 10 days plus. My girls have a coop and I made them a cookie tin heated waterer, my question is are they really going to be okay with this being such an abnormally cold time here? I've seen from the folks who live in the more northern climates that they don't provide heat for their chickens and they do fine. I'm just concerned that my southern belle chickens may not be ready for this stuff because they are certainly not used to it.
