So I made a waterer with a 5 gallon pail and 4 water nipples in the bottom. Hung it in the run. I also have 2 1-gallon gravity waterers out there. So far, chickens have not caught on to fact that water comes out the nipples, haven't even seen one peck at them even when standing under it. Any thoughts on how long it will take for them to catch on? Its been in the run for 1 week. BTW, I can't remove the 2 1-glln waterers from the run, its too hot to take a chance on them not having any water if they don't catch on to the nipples.. Thanks!
