Can someone help me with sexing these two mallards?

Only one is getting green

Yeah, the green feathers on the head is the #1 indicator of it being a drake. And the other should have them by now, too. So I'd bet money you have a pair! The bill will turn, too, as mentioned above and then the curly tail feather will come in too. You can google that to see what it looks like ;-)

Well thanks for the help everyone! I really do hope i have a pair since I already have another drake and hen.

They look like they are both drakes as ducks don't have the same feathering as drakes.

Any closer to an answer? I’m still unsure with mine. Mine look the same, with green sheen on top, but all mine quack. You’re a few weeks ahead of me and I’d be interested in how yours turned out.

Do you have any photos of them?

I’ve posted my own thread on this. I was just wondering about the OP’s results here.

They both turned out to be Drakes

When you hear quacking then you have females drakes sound like heavy smokers.
