My female khaki runner lost her companion to a hawk attack about three weeks ago… I found another runner in the area that was put up for adoption, it is a black male runner. I quarantined him and decided to let him run around the yard next to the female in her caged in run so they could meet. she was very aggressive and tried to attack him through the wire so i separated them again. I’ve been trying to get them to get along by putting them in the yard together in intervals, each time i do, my female khaki bites him and pulls his feathers… what do i do ?
