We have a 3 gallon waterer..plastic w/ the red bottom / tray and black screw on lid...we love this waterer..has worked great for us... can we continue using it this winter? how would we keep it from freezing? We really want to keep it hanging too so the water stays clean.. Thanks! 10/13....a friend that has this same kind of waterer came up with the following idea... Getting a heat lamp that has the "cage" on it so that the chickens can't fly up into the bulb and break it and then putting that near by the waterer to keep it from freezing.... thoughts on this??
