I have a 5 gal Dura Fount plastic waterer that everytime I put water in it, it just keeps filling the bowl on the bottom. I'm not sure what is wrong with the cotton picking thing. Has anyone else had a problem with them? How can I fix it? My chickens have a 1 gal galvanized steel waterer now that I want to get rid of. I'm sure it makes there water taste funny. I also have heard that I need to put ACV in there water and I can't do that with the steel. Help!
