Has anyone else had this same problem? I bought chicken nipples for my 3 hens. Installed them in a juice bottle. Chickens loved them, I loved them. For 2 days I checked on them several times a day. Then, yesterday I didnt. That evening I went out to check on them one flew out of the coop, found some rainwater collected in a toy and started gulping it down. Yep- chickens can gulp. Finally we figured it out- the waterers looked full, but didnt work because they were sealed and had suction holding the water in. (I had figured they would be like hamster waterbottles- suction is what prevents leaks) I poked holes in the tops of my waterers. They work again. But I am scared. I am still nervous about taking out the bowl of water (the one I hate because they tip it over or poop in it). Anyone have experience with this?
