I have 3 red caps(1 male, 2 female), I am thinking about getting 2 more but not sure. I already have a Pair that lays eggs and a female that's a 3rd wheel so I'm not sure if I want 2 males 2 females or 1 of each. If another pair forms I will still have an outcast, I would rather have 2 sajica than buy to more and still have outcast. Any suggestions?
