What Gender are My Ducklings? - I’M BACK

[_Featherian]

Hello everybody
I haven’t been on BYC for quite a few months now. Maybe a year, I don’t know. But I’m back and hatched two mallard ducklings 2-3 months ago and don’t know what gender are they. Could you guys tell by the picture? Thank youuu

I think females based on their bills, but the only sure way to tell before they get adult plumage is by voice. These may be a little young for that. Generally they get their adult voices after 10 weeks, but it can be later. I've posted a link that shows how to tell gender by voice. There are many others on Youtube.
