Breeding season has just started. The male's producing his manly stuff and crowing now, but now there's tension between the girls. They're coturnix quail, ratio one male to four females. I don't think space is an issue. My biggest one, Pepper II, always pecks at my smallest, Egglantine every time she walks past. She also pecks at the other girls when it comes to treat time, which she normally does, but this time she seems a little more aggressive. Then Egglantine pecks at her sister, Willow, and pretty much only Willow, who is bigger in size than her, when she walks past. My forth female, Buttons, doesn't get pecked, but seems to be scared for the sake of it. There's no blood shed or anything, just tugging of feathers. Willow seems to be missing a few small feathers. Is this pecking order being reestablished? Becoming territorial because of breeding season? Or is it racism/bullying? Thanks.
