I've been using a nipple waterer for several months and like it. Today was the second time I went into the coop and all the water had spilt out. It was still hanging so no it didn't tip over. The lid was still on. No hole in the bottom. When I filled it back up no water coming out of a hole on the side. I don't understand. Can one of the nipples get in a position to keep dripping even when the girls aren't drinking. I've had this for several months and this is only the second time it's happened so it must be something that the girls are doing to it or something sticking??? So any ideas? Has anyone had this problem and what did you do about it? I was so happy I thought I finally found a water to water my flock that was clean and wouldn't get tipped over and have water everywhere. Sorry to start a new thread but I didn't find anything on problems with waterers.
