Yes, those hanging bottles a few people were raving about as day-old chicks were catching on to those; however, then comes the wet mess, so it's not helping keeping the coop/brooder dry, which is part of their purpose.So I tried to switch to those nipples but I have one chick that is not growing while the others are 2 times the size so she wasn't able to get water I don't think. So I switched to the nipple that hangs down but that is making a mess! I bought the self filling cup from rent a coop and that should be here tomorrow so hoping that works better.
Ours took two weeks for the horizontal ones, mainly, I think because they're too little to push that metal rod to get water. Then I sit the container on a 2x4 to get it "beak level." I showed them, then removed other water sources, so they went back to it and pecked until they figured it out.
