how introduce ducks to eachother?

[JNC]

I have 5 week old pekin ducks and just today I got 3 more ducklings. I’m not sure what breed the new ducklings are but they are definitely not pekins. When i was showing my older ducks the new ducklings we had they started vibrating their head and trying to like pick at them. Will they ever get used to eachother and how do I get them to get used to eachother. Help needed ASAP

Keep them separated by a fence for a few weeks so they become more familiar before trying to combine them.
