The chicks have figured out the water bottle I attached to their cage yesterday and have become quite adept at using it. This is a very good thing, as they kept knocking over their water dispenser and fouling the water by kicking litter into it. When we switched to a trough, the water really got nasty. The hamster bottle mounted to the outside of the cage solves both problems. I highly recommend it for anyone trying to figure out how to supply clean water to young chickens.
