Two males, and plan to get a couple more one day when I figure out how to fit another FN cage in my tiny computer room or get another ac so I can have them in another room.
I've had both males and females before though.
I have 9 males. The first pair I aquired were boys, and as I am not interested in breeding, a mix of males and females didn't seem appropriate. That said, I'd love a pair of girl chins. :wink2:
