I've been using a heated dog water dish for water. Problem is, one hen wants to roost on it. She started by standing on the edge, now she sits in it like its a nest. I don't know if she gets her feathers wet or not. Needless to say, the water gets poopy. I tried sticking a beer bottle in there to make it uncomfortable to sit on. The water was still dirty this morning. I am wondering if this is the one who has much yellower legs than the other hens. I've got over 8 feet of 2x4 for 4 hens and a rooster for roosts. I have been meaning to rework this to try to get it higher. Right now they seem to want to use nest boxes. The water dish is just off the floor on a cement block.
