We’ve had these 4 ducklings for about a month and their noises are starting to change so I’d love some guesses on genders!

There’s a good chance all of them are girls!

2 and 4 are the easiest to tell with those honks. 1’s a bit harder, but I still think she’s a girl. 3’s the hardest for me, but I can definitely make out some peep-honking; hopefully that will continue!

Boys won’t have much of a voice change until they’re around 8 - 10 weeks. Girls get their voices early on and are very, very loud!!
