just out some anti freeze in the water no big deal
won't work if you really live where it gets below freezing. I promise you that it will freeze just as fast as the one with no insulation or salt water bottle or whatever else you dream up.
I agree, great idea, I have large truck tires (48 in. tall) that I will put in the pen for bulk solar heating. I have spare tires laying around for the waters. Just had to buy the black stock feeders and a few balls.
awesome idea. I am going to try it for my outside dog. :)
I'm going to do the tire trick tomorrow for my chickens
I'm going to try this. You think a handful of ping pong balls would work better than that big ball?
That is brilliant. We got temps here in NC that went down to 7 degrees and our chicken water kept freezing. I put a waterer in the mobile coop and buried it in the bedding and it stayed thawed, so I was thinking of building some box with insulation in it. The tire is a much better idea. Thanks for sharing!
