Introducing sucks to pond

[clairesmom]

Hey everyone. I'm new to the site and need some help. I have 4 ducks I've raised since they were 2 days. I have them a pen outside with a baby pool in it. They have water experience since young age. They are now old enough and ready to move to the pond. Which is in my backyard close by. I was wondering the easiest way to introduce them to the pond. A way that's not going to scare them when I have to catch them all and move them. I'm working on their housing for out there now.
Thanks for all your help.
