I have been offered a non-releasable baby flyer as a potential companion for my little 2 yr old female, Pixie (hand raised). I have heard that you can successfully keep 2 of different ages together if you do the introduction properly. I have a female who has seizures and the baby male I would get has hind leg mobility issues (although he is not paralyzed). My girl is sweet and pretty mellow. I plan to have the baby separate until he is large enough to hold his own, and after he has bonded to me. Any advice would be very appreciated because I think this could be really great for Pixie. She had not been able to spend a lot if time outside of her cage because of her seizures and I think this could be mutually beneficial.
