Hi everyone, I'm trying to figure out if anyone can determine if one of my ~6 month old Pekin ducks is a male or a female. I'm pretty sure about one of them, but not sure about the other. I got them both at the same time, one appears to already have his drake feather, the other one I can't tell. Please take a moment and see if you can tell. The duck with the light bill is a male in my opinion, not sure about the duck with the dark bill. Thanks!
