I have this wierd idea of having an open bucket attached to the outside of my coop and using a small hose of some sort to water a container inside the coop the chickens drink out of. The main reason is to catch rainwater, the only way i can think of to do this is to use some kinda float valve. I know it's not really a winter friendly idea but it'd be a good way to save water. lol Maybe use the one water source to fill the water inside and outside the coop? Anyone got any ideas? [Edit] and I'm not sure if my chickens will be able to learn to drink from nipple kinda things.
