Help! Is my muscovy a boy or girl? Almost a year old.

[DakotaDreamer]

About 3 - 3 1/2 months ago I bought 3 muscovy females after finding out that two of my four ducklings were drakes. I think that Venus is a girl but am not sure. A little info on Venus: She was born in October 2016, she weighs 6.6lbs, she keeps mounting all of my ducks(except boys), I do not know if she has layed an egg yet but she is the only one of my three muscovies that isn't broody. As a comparison, my other two muscovies that I got from the same farm and are shown in the pictures below weigh 5.6lbs(Comet) and I have an extremely tiny one who weighs only 3.5 lbs(Nebula). None of them have grown since coming to my farm. Nebula started laying about 2 months ago and Comet started laying about 1 month ago. They are starting to molt and I haven't been getting any eggs from my 7 female ducks since. Venus, who is my one in question, is also the most aggressive of my ducks. She will thrust her head foward while hissing and bite my ducks. I can't go off of voice because all three have never cooed before. All three mostly hiss, I have only heard once a different sound from Comet and Venus and little Nebula goes around pipping during the day. None of them have bright red masks either, they are all pinkish - red. I hope that this is enough info. Thanks to anyone who helps. If you need more info I will be glad to share it.

Thanks again for all your help. If more photos or info is needed let me know.

Hmm The size is saying female but everything else is saying boy.

What would cause it to be aggressive? It has never mounted one of my girls in the water and the girls always run from it when it attempts to mount it. There is no reason for the aggression. None of the ducks challenge Venus and neither do the chickens( including my roo). Comet does the head thrusts sometimes as well.
