How long before ducklings can go outside?

[Newbie_Hatcher]

My aylesbury ducks are due to hatch in a little under 2 weeks, and I was wondering how long it is before they can go outside and swim unaided?
I'm in the UK so its pretty cold at the moment. Thanks!

the longer you can wait the better. You want them to have their full set of real feathers and be rid of all the down. I learned the hard way to limit their access to water early on. I had one get in the baby pool, got to tired to get out and it drown. I didn't realize this could happen.
