What other method you think is best for introduction ( 8yo & a Joey ). Other than the common way.
I have an 8 year old female who just lost her cage mate a year ago and wanting to intro a Joey to her. There's some complications where vet advised it's best to not have her a cage mate but now she is overgrooming and I think that alone option doesn't worked anymore and so I decided to chose the gentle ones among my new colony for her.
As I know it's difficult to intro an old to a young but I have no other options. So would appreciate a suggestions from people who are experienced here.
