I know I've heard of people using the rodent water bottles (with the balls in them) for their quail. I'm hoping to be able to use this, because mine are kicking crap into their waterers. I've even tried covering half of the cage with cardboard so that there wasn't bedding anywhere near the waterer, but, nope, they somehow manage to kick it across the cardboard and get it right into the waterer within a few hours. I'm tired of dumping and scrubbing the stupid water things 4 times a day. Anyways, who uses these water bottles, and are they for coturnix or buttons? Was it hard to teach them to use it, or do they naturally peck at it since it's shiney? How old do the quail have to be when can you start to use them? I really hope I can use them for the quail, for $1.82 for one, it's cheaper than the quail waterers, doesn't take up cage space, would be easier to monitor, would be cleaner, and I wouldn't have to modify it to get it to work properly. Plus, I could just melt a hole in the sterilite containers that I plan to use (after minor modifications) to hang them easily on the outside.
