I had 1 red legged partridge who's mate died she's a female, I got two a pair of a guy who said they'd get along fine, for the first day they were hanging out around the avairy (25ft by 10ft) together. And know the male goes around biting the partridges neck. I don't have a spare cage or anything so I gave the male a string in his foot so he stay on one side of the aviary, with access to food, while the two females just hang out and eat food together. Is they're anyway I can get rid of his aggresion
