for the last three days one of my female quails has been viciously attacking the male (i have one male, three females, in a coop 6'x2'). he's taken to hiding at the back of the coop and as soon as you approach, she wakes up and goes straight to the back and starts attacking him. he's lost quite a few feathers already and she's showing no signs of letting off. the other two girls are trying to stay out of the way. any ideas why this might be happening and what i should do? i could segregate one for a day or so, but not permanently. would that help, and which one? thanks.
