So i have 10 coturnix quail as my pets ( what cool little birds. ) but i have had lots of problems with them bullying each other. I have 2 males and 8 females. One of the males started being cruel to the others, and he scalped the other male and a female, so i removed him, so now i have 1 male and 8 females. All has seemed well since then, but recently the other male has begun to attack the females and the back of their heads are bloody and plucked. Is this mating behavior, because it seems awefully graphic and bloody. Are these birds simply mean to each other no matter what? And finally, should i remove the other male? Are all male coturnix like this? Thank you so much for any answers.
