I was pondering the water question. I know we have overnight freezing temps and I used to chop ice in the water troughs for the horses for a few months. Now I have heated trough. So knowing that the water trough freezes, should I suspect my chicken waters to freeze? What if they are in the coop with the chickens? The trough is out in the open pasture. Should I put electric in the coop or would that just be a waste of my time and money? I have the wire but need all the other stuff. Plus digging the trench which is a pain in my back as we dug the one for the horse barn. Would building a box and putting insulation in the box and then a top with a hole cut so the chickens could drink out of it work?
