I made a nipple waterer, 5 gallon bucket and 3 push in nipples. The thing is working but the chickens don't seem to get it. I "showed" it to them in pushing my finger there so they can see the water dripping down. That was yesterday in the morning and of course they came running like wild because they where thirsty but then they tried it and soon gave up. It seems that they can only get a tiny little drop and then get frustrated and leave. When I let them outside to free range (which they do all day) they storm to the regular waterer as if they hadn't had anything to drink in days. Same thing today, almost all of them tried the nipple waterer but they it seems they give up when only a tiny little drop comes out. Do they ever get it???? How long does it take??????
