first of all i have 13 coturnix quail. they started laying about 4 wks ago. we separated all the males but two out of the breeding pen. before that we were getting 6 eggs a day and for about a wk after we were getting 6 eggs. we also banded all of the males. after about 2 wks, another one started crowing that was not banded. then we started getting only 5 eggs. is it possible that one of the hens switched sexes? there were 6 hens and 2 males in the breeding pen after we separated the extra males out.
