Breed? Age? Gender?

[HighMeadowFarm]

Hi,

I've purchased 17 week old pullets before but this is my first time having chicks.
I've had them about 3 weeks but don't know how old they were when I got them, also don't know their sex or breed.

I know the younger ones are: Astralorps, Silver Wyandotte and Americana.

Any thoughts are appreciated!

Thank you!

About 5 weeks old.

I’d say 4 weeks old, the first pics of the black one is probably a male but it would depend on the breed. Sorry, I don’t know what breeds but they sure are adorable!
