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
