any ideas on the sex of these runners?

I hatched them not too long ago, i havent heared any loud quacking yet.
i tried moving them to the adult area & they were pounced on immed by my muscovy male- i couldnt tel if it was mating or fighting lol.

theyre heads & bills are different, one bill is very straight, the other curves upwards. Also- i dont see a curl at either of their bottoms.

and just for cuteness--here they are as babies

They're adorable! How old are they? That would help a lot in figuring out gender.

I don't see curly tail feathers either, so that's a good sign. But it seems like they'd be quacking if they were girls, so it's hard to say. Have you tried picking them up to see if they quack?

I love their creamy white color. They are beautiful.
