Hello everybody. I am new to owning quails, it has been 2 weeks since I got them. We have 4 female and 1 male coturnix quails. They are in a coop of size(LxWxH) 1560x520x680mm. They are around 5 to 6 weeks old. We had one egg so far and then no more after that. One of the females keeps pecking on the metal fence and her beak is bleeding pretty badly. The females are also running away from the male pretty frantically. Nobody is pecking her as far as we can see. We think that maybe this is happening because the male stresses her. Or maybe they don't have any entertainment? Is the coop not big enough? I am attaching the video and photo of their behavior. Pls help!
