hi so i have 6 quail. 2 boys and 4 girls. one of my males is very aggressive and the other is pretty passive. the digressive one is barred of from the other birds by a net, but is still able to see and hear them. What i'm wondering is why they aren't crowing. It is breeding season and i'm getting fertile eggs. yet I'm hearing no crowing. Not that I like their crowing that much, I was just wondering if something is wrong.
