Muscovy duck gender unable to identify

[Vanshi]

It has been 8 months since I bought a pair of muscoy ducklings. Till now even as an adult, whether they are male or female is a doubt

Some pictures would help.

Females are smaller, weighing around 5-7 lbs, make sweet chirps and whistles, and have smaller face masks.

Males are much larger, some weighing up to 15 lbs, huff and puff, and have large, bumpy face masks.

Thank you so much

I'm trying to attach files of the pictures. But it's not working

I'll try my best to upload pictures here. I couldn't change my profile too. I'm logging in after 3 years

Now I'm able to upload pictures. I'm unable to identify the gender. It has been 8 months since I bought them as ducklings

First pic is 8 months ago. And other pics are now

Oh, so sorry! I didn’t see this.
I want to say both female? But I’m uncertain. @ruthhope may know better.

If they are both the same size, use vocals to determine sex. At 8 months males will only huff. Females will make a hiss similar to a huff, but only when irritated or broody.

If the photos of the carruncles are in year old muscovy, they are probably females. Male muscovy by a year old will weigh 12 or more pounds weight. They have broad tails that they can fan out, but they don't always fan out their tail feathers. They will only be huffing and puffing -- particularly when excited. They will have a full face of carruncles and as they go into their first breeding season may even get carruncles on the back of their neck, sometimes in chevron distribution.

Females will be only 7-8 lbs weight, and will make gurgling sounds not huffing and puffing when excited. No carruncles on the back of their neck and only outlining their eye and bill, not full face. Little pointed butt ends.
