I recently started volunteering at a rescue. I have Muscovy ducks and don't know all the other breeds. Could someone please give me an opinion on the breed, sex, and if possible age of these ducks. The white ones are all different ducks. The dark one in the last 2 pics is the same duck.

Pic 1: Both Pekin Drakes
Pic 2: Two Khaki Campbell Drake's and hen Pekin or White Layer (it's hard to tell the bill color)
Pic 3: Pekin or White Layer hen and either a mix or Golden 300. Not sure about the last ones sex I see no tail curl so I'm assuming hen. Does this one make a honky quack noise or is it more raspy?

The drake will have the curl feathers above the tail
For age 4 months at minimum to show the drake feather
Are you getting any eggs ? Of do at least 4-5 months for that

Thanks for the info. I asked today and was told there have been no eggs.

The last one looks like a Muscovy mule hybrid.

Ok I would say the girls are under 5 months
If the ducks are all the same age I would say between 4-5 months

I agree
