I know there are so many "how to winterize my coop" threads, but I think it pretty much have it handled. . My question is, can I use a rice heater? Its a sack full of rice that you put in the microwave for a few minutes and it stays warm for a while. I was thinking about making 2 of them, and have them a few pounds each. That way I could put them on either side of the coop. The coop is well ventilated, so I don't think the moisture would be a problem. Its about 6 inches off the ground with a plywood floor and about 5 inches of pine bedding. I was thinking that I could put it under the bedding so it would radiate a little heat for them. I know they're going to dig down into the bedding a little, because they're already doing it. I was also thinking of getting a bale of hay and putting some hay on top of their bedding, so if I put the rice warmers in, I could put them under the hay? So would that be alright or would it be a waste of time? What do you guys think? Thanks!
