I have recently made some hanging waterers using chicken nipples and 5 gallon buckets. They work great and I have one inside the coop and one outside the coop. I managed to get the chickens trained on the watere outside the coop and figured seeing they look identical that they would figure out the one inside the coop as well. However, when they come out in the mornings, they run straight to the outside waterer and drink as though they are dying of thirst! I have to assume they are not drinking from the other waterer inside the coop. They also don't like me being inside the coop, so I can't show them how to use it. Has anyone else had this problem? How can I get them to use the one in the coop as well, as I don't want them to go thirsty during the night. Thanks!
