We had 20 quail chicks hatch at the beginning of the month. One of them was much smaller than the others and didn't seem to be eating properly - sadly it died after a couple of days.
We still have 19 of them. This morning we thought we might have lost a couple because we found 2 soggy half-drowned chicks in their drinking water. We knew that quail were stupid birds and had been putting marbles in the water so they could get their beaks in to drink, but not get their whole heads in to drown. The chicks shouldn't have been small enough to fit in the water trough. Somehow two of the smallest managed to get in but not climb out again. A third chick looked like it had been in the water but had managed to get out on its own.
We dried them out and kept them warm and they seem to be doing ok now. We've also put the marbles back in the water to stop it happening again.
