How to best migrate a single hatch duckling

[baust3217]

I have a Khaki/Cayuga duckling trio that all hatched within a day or so of each other living happily together in a small garage coop. About 5 weeks old. I also have an almost three week old Muscovy duckling living in a brooder inside. Their size is quite different but my little Muscovy is running out of space and she’s becoming more and more dependent on me (no problem for me at all!) but my fear, based on past single hatched, she won’t adapt to the general flock when the time comes. Any advice in pulling the 4 together would be helpful. I’d be devastated if they hurt her.

I would start by penning them next to one another. Initially she will be scared of them which can invite aggression. Another problem she will face is that she 'speaks' a different language than the mallard derived ducklings.
