yeah, those are sex-links so the color alone will tell you the gender, they are definitely girls

Definitely a Sexlink pullet.

Not that everyone hasn't already made it clear for you, but I'm jumping on the bandwagon - female black sex-link. I have an Australorp hen and she looks similar, but they don't have any brown in them at all, from what I've seen - only black with that green sheen to them. The sex-links will have the brown coloring mixed in, often times. I'm a relative novice, but in comparing mine to yours, that's the feedback I can offer!

That is definitely a girl!
