The quail at the front has a bulbous vent with foam and a little comes out on its poo! The quail at the back - Its vent is not bulbous and has no foam! Now, I know by that they are meant to be male at the front and female at the back. But, by the looks of them they are female at the front and male at the back. Does a male Coturnix have a flat vent area when not in season? Now, to confuse matters, these quail are in a different cage than they are usually and are fine towards each other. The cage/ aviary they are normally in with other Coturnix Quail, the quail at the back cases the one at the front almost constantly. Help!
