I have a male Pharoh quail and a female pharoh quail. im positive they are male and female. one lays eggs. the other has the red coloring on its belly. The vet even said they were boy and girl. They are in the same cage. only them two in it. always fresh food and water. they are not mating. they get along and sleep by each other. but thats it. y could be the reason there not mating. im poitive there not. i watch them. put a camera on them. i know there not. What could cause this??
