How to tell if muscovies are mixed?

[ruthhope]

Not only was

The female also ridiculously small for 6-8 weeks and then caught up

She was extremely skittish and frightened of me, dashing to hide behind her much bigger clutch mate when ever I approached. By the time they were released, she was the boss!!! She was keeping order in the pen she had been staying in.

We have a flock of muscovies. We just got given 2 free ducklings yesterday but we're on the fence about them being full? We were told they are about 8-10 weeks, which if they're full muscovies can't be true with size & feathering. I'd put them at 4-6 weeks. We aren't too fussed either way but more so curiosity. I do know mixed muscovies are infertile, so we'd likely only keep the girl for that reason. If anyone can assist in what they think I'd appreciate it! The last photo is them with some of our grown adults & some of our 8 week old babies (8 week olds are the 2 to the left & the one below) to grasp how small they are haha.

I don't know if they are pure muscovy. But they look cute!! I think the down doesn't preclude them being 8 weeks old as some muscovy ducklings, even when fed and cared for properly [in my bathtub when they outgrew my brooder before they were able to go outside!!!] are slow to feather.

I do not have experience of mixed muscovy+mallard but these two are already developing carruncles. Perhaps someone who has raised mixed muscovy can weigh in on when they go their carruncles

Mine got the line of caruncles like that around their bills but it never developed further.

The two in the centre and the black-headed white just behind.

I had Chocolates and blacks with weird white patterns, and capped whites with odd spots on their bodies. They all grew to be HUGE and quacked quite loudly, but the caruncles never developed further than the edges.
