These chicks are a mystery to us newbies. Do you think that they are roo or hen? they are about 10 wks.

The first pictures i would guess Americana. I see greenish legs.
The last one is a silky.

From these pictures they seem to be pullets. 2 easter eggers and 1 silkie.

Silkie is probably too young, but doesn't scream male yet. Both others look female

Two Easter Egger pullets and a probable silky pullet.

Yes, they look like Americauna pullets and show greenish feet. They would show more comb and be more cock like (rangy) by this age if they were roos.
Agree, last one looks like a young silkie. Maybe a pullet, but a bit young to tell.
