I was using an auto waterer for birds, but they still kept getting crap in the little trough thingie. So I put up one of my rabbit water bottles, with a bit of honey in the water. I brought the rooster up to it, and pushed his beak into the nozzle. He like that very much. Then all the others had to try it out. I then switched to regular water, and they are all still drinking from it. I wish I could train my chicken to drink this way.
