I guess the subject says it all.. I have 15 buttons, no room in the house for 7 or 8 cages, a high ratio of males to females, and even if I did pairs, I would have a lone button or a trio. Has anyone here ever successfully housed them in larger groups? Would it just be a matter of floor space and hiding spots, or is it a disaster waiting to happen? I think these guys are 4-5 weeks old now, but my memory is hazy.
