Pet ducks !?

Question

i have two pet ducks.

juno & bleekers.

i know them apart, and they are the same species of ducks..

but i don't know how old they have to be to be able to tell their s*x.

they are khaki, and almost two months old.

how can i tell they're genders ?

Answer 1

blood test/sexed

Answer 2

listen to their quacks. if its sharp and a little obnoxious, then its female. if its soft and deep, then its a male.

or you could wait until they get their feathers. males have green heads like mallards and females are tan/brown
