The white one looks female - I think the other one is too, but can't really see its legs.
Do you have a better pic with the body and legs?
How do they contradict themselves?
At 5 months, if one was a drake, the differences in body size would be quite obvious. I am going to say both females. Unless the one is hiding a lot of body.
Thanks everyone for the help - really keen to find out!
Yes I made the same post a month ago and everyone said girl but lately the caruncles have been growing quickly and I feel like I've been hearing one make the huffing sound usually described as a male attribute, so am not sure!
(Thought this new photo could with a size comparison to a person)
As for contradicting it's just that they having been showing attributes of both male and female each, so whenever I start thinking one thing they start to act like the other
Thanks for all your help though - have never owned ducks before
@muscovymumma If you take a video of your girls, we might be able to help you with the sounds you are hearing. You would have to upload the video to YouTube, Facebook, vimeo, etc before posting here.
Muscovy actually make a handful of sounds. One that I find interesting is a honk like quack - especially if another one is bothering them.
