I have 6 Rouen ducklings. These are the first ducks I have ever owned. I have them in a baby play pen, but they're quickly outgrowing it. I don't know how old my ducklings are, but I'm guessing around 3-4 weeks. They are starting to get their adult feathers on their tails and chest. I would like to ask a few questions and get any advice you may have.
When did you move your ducklings outside? What age? What was the temperature outside? What did you brood them in?
I also have a couple of ducklings that are developing a white ring around their neck. I have included a pictures of the duckling that have the most pronounced white ring. Does this mean these 2 ducklings are drakes?

And just for fun here is a photo of all six when I first got them.
