That's very helpful- getting the perspective from a private breeder. And it's what I suspected, that some quail attack each other, but without direct quail experience I couldn't say. I know I've even seen free-ranging chickens that will pick on & badly injure one of their own (chicks) for no apparent reason (with plenty of food & space), so I just figured quail might also do similar things. When large numbers of poultry or game birds are raised, maybe you have to expect some injuries, & it would make little sense to waste them when they're being fed as prey animals. It's right to ask questions though.
