Winter is quickly approaching and this is our first year with "backyard chickens". Five to be exact, in our small 4'x4'x4' coop. We live in Michigan where it will get into the teens during the night and can even get into single digits. I'm worrying about how we will water our chickens. I came up with a "cookie tin" heater to sit a waterer on, but I'm worried about water and electric even with a GFCI breaker. I made a 5 gallon bucket with pvc pipe and nipples waterer this spring and I love it. I wish there was a way to keep it going all winter. Attached are some pictures of it. I'm "wondering" if it would be possible to keep it going by having a bird bath heater or an aquarium heater in it? But the heater would also have to keep the water in the short (about 24" long) PVC pipe from freezing too. Is there any possibility of this working? I'm on a VERY tight budget, so I could probably purchase the bird bath heater but that would be it. Any thoughts/suggestions??? Thank you!
