Sexting my ducks?

[Perla_Berlanga24]

Can anyone tell by the picture if my ducks are either males or females? Got them back in the beginning of April. 3 of them have a raspy quack and one of them have a louder clear quack. Kind of thinking I have 3 drake's and 1 duck but just want other opinions thanks!

No you can't sex pekin ducks by looks when they're still too young for sex feather. You may be able to sex them by size but the difference can be subtle. Judging from your description I believe you've voice-sexed them correctly.
