Another Muscovy Duck Sexing Question (AKA astrology)

[Rafnel]

Hi everyone. We got 2 muscovy ducks today to add to our flock of 2 black swedish ducks (you may remember my post from July about free ranging my flock). The muscovies, according to the farmer, are about 3 months old. He believes they're both female, but he even said "you don't know for sure until they're either crowing or laying eggs" (making a joke about chickens/roosters). So I'd like to posit this to you folks with some pictures attached.

Some extra descriptions to help:

- Both are doing very clear, very frequent trilling (female trait?)
- they have large fan-like tail feathers (male trait?)
- Caruncles are mostly undeveloped, just a small ring around their faces, no warty bits yet(female trait?)
- both are same size (so they must be same sex IMO)

I want to believe they're definitely female. Any thoughts?

They are beautiful! Based on the pictures (and I'm often wrong from that, lol) I think they are female. Mostly basing this on the shape of their heads and necks, as they look nice and dainty and, well, feminine!

I don't trust the tail thing, I've found it wrong most of the time.

Sweet!! Hope we're right
