Waterer Base 1Quart Quail Base

So, my loving and thoughtful husband knew I was trying to figure out a way for my suicidal quail hatchlings to drink water without drowning themselves. The next time he went to our local feed store for pig and chicken feed he asked them if they had any such thing as a "quail waterer", and here this item appeared. Never heard of such a thing. Seems genius due to it's small size, and narrow sides. But, apparently my quail are too "smart" to be fooled by such a thing and dove right in. We lost one baby unfortunately, and had 7 others completely soaked. I now fill the bottom of this with marbles, like any other dish for quail and take it out most nights, just to be sure there are no accidents. Overall, great concept/idea, just needs to be more shallow in my opinion because if the little ones do fall in they get stuck due to the high sides and narrow walls. Adding marbles to the bottom, as usual helps. But then it makes it just like every other water dish we make for quails, lol, just holds more water I suppose.
