I just bought one of those water heaters to use with my steel waterer. You know, the plug-in platform from TSC? I bought it out with every intention of placing it on the coop floor and plugging it in. Then I started thinking that it could be a fire hazard... Just plug it in, right? I CANNOT DO IT. Should I place it on a piece of wood? Is it okay right on the floor with the pine shavings? Please, veteran chickie farmers tell me what to do. Thanks.
