Duckling introductions

[TJakeman]

My wife decided that it was time for us to get some ducks to add to our animals. And she came home with 6 pekin ducks, they are now a week old and live in their brooder at the moment. While I was out earlier I bought another 2 ducks, of unknown breed, they are only 3 days old and alot smaller than the pekins. Would it be okay to put them all together or is it best to wait until they are older, and what is the best way to introduce them all together.
Thanks in advance

If the new ducklings are much smaller than the pekins I'd keep them separate cause the bigger ducklings might squish the little ones

Maybe keep them in separate brooders next to each other so they can hear each other, they will start to get them used to each other
