So happy those little babies made it ok! They are super cute

Hopefully they will calm down and stop picking on each other, I'm sure they were pretty stressed being in the shipping box for that extra time.
For our 1st ducklings we used a large cardboard box (we had just gotten a new stove) it was 3'x3' I think. And we lined it with a heavy plastic tablecloth and used zipties to secure it. Not the prettiest but it worked and held up and best of all it was cheap.
I know some people do keep house ducks...im glad ducks are so messy or I would have been tempted with our 1st pair...tiny little poop monsters

My biggest concern (besides seperating the babies) would be that they would get into something and eat something they weren't supposed to in the house. They love to forage and tiny toy pieces, earrings etc. that are accidentally dropped would be a hazard if eaten.
We only have runners but I do feel like they are pretty smart as far as ducks go, easy to train for simple tasks. We don't have any other breed to compare them to though.
They should imprint on you well, just spend lots of time with them. Our babies are super friendly with my husband and I but shy and nervous around anyone they don't know.
So very glad they made it ok! You're going to have so much fun with them
