Questions about my ducks

[acrana]

I have a Mallard that is about 3 and half months. I'm trying to decide her sex since at first we thought it was a girl but now she has a drake feather.

Also I got 3 Ducks from someone while back I'm thinking they are a rouen mix ducks

Oh yes, it's a boy. They change colors a lot. He will get the male colors when mating season starts.

I think the dark coloured duck standing at the back of the pic above is a runner or runner mix. Not sure about the other two. K is right about the mallard.

You can tell on his stomach too. The male pattern is starting to show. He is going to be beautiful!

Yes, definitely a boy. You can also tell by their bills as they get yellower as they reach adulthood. He already looks very pretty.
