I am wanting to purchase a double wall water fount for my chickens, however, after doing a lot of searching on here, it seems that a lot of people have problems with them not sealing properly. I am wondering if this is a problem with a specific brand or this style of waterer in particular. Is there any one brand that works better than another? I am getting tired of trying to find a watering solution that works well for us. I thought it would be nice as I could put a heater under it for winter as well. Any suggestions on a good, reliable brand that works? Thanks.
