Hi I have 2 Barbary partridge hens due to arrive Wednesday and then 2 male Barbarys due to arrive some time next week. I have a cage that is 4' long x 2' wide. Is that large enough for 2 pairs? If there is only 1 week between the time the girls will be in the cage to when I will introduce the boys, is that enough to where the girls might attack the boys due to territory? Would it be necessary for me to keep the females in a small temporary cage until the boys arrive them introduce them all into the 4x2 cage?
