Hi all, they are around 3 weeks old. Can i have some advice if the 3 of them are male or female, thanks!

They don't look like they're three weeks old yet. I suspect that the one on the far right is male. The other two aren't feather sexable. The first one looks like grau fee for colour.

Thank you! I suspect the one on the right is male too, then the other two are females. Learnt something new today (Grau Fee)
