When I got Nutmeg I didn't do split caging.
I cleaned Hatty's cage and took some of the of the old
stuffing( Care Fresh) and put it in the little cage I had Nutmeg
in. After she dug around in the stuffing I rubbed the rest on
her so she would smell like Hatty. I put Nutmeg in Hatty's
clean cage and left Hatty out. After Nutmeg had been in there for
awhile and used everything(so her smell would be there first) I put Hatty
in. It was rough at first, but now their the best of friends! The place
were we got Hatty and Nutmeg from suggested this. I hope this was
helpful in any way!
