Khaki Campbell- what gender?

[lps1215]

Hi, I got these Khaki Campbell ducklings yesterday. I was told they were 5 months old. Does anyone have a clue for if I have females in the group. The only difference I have been able to tell is one has a beak that is light more yellow than the others. Thanks

Does the one quack or sound like the others?

One seems more frog like than the others. I've tried not to mess with them much since I just brought them home. I didn't know if someone could tell by feather coloring even though they all look pretty similar.

They still have juvenile feathering, I believe. All look to be female so far. I questions whether these are actually 5 months old, as they seem quite a bit younger to me. Males will have a curled feather on top of the tail, but it is too early for that. But it's not too early to tell gender by voice, since males and females sound different. Here is a good video that shows the difference:

The female has a black beak and the male has a dark green beak, I don't think they have 5 months old, at 5 month old they should lay eggs.
