Introducing a new duckling! Any advice?

[MissTeal]

I have an adorable duckling, he's about 3 or 4 weeks old with his oil just barely starting to come in. His name is Cheepers and he was given to me as a birthday gift and while I have plenty of time to give him and he has imprinted on me I feel that he would be happier with a friend. Now before I go buy another duckling(it will probably be younger, a week old I'm guessing unless there is one around Cheepers age) can anyone give me pointers on how and when to introduce them safely? I already have all the things I need to keep them separate if I have to.

Separate the brooder with wire and let them get used to each other first...

Let them out for supervised visits and soon they will be Pals...
