What genders are my chickens?

[Sxftiechicken]

I have 4 chickens that we have no idea what gender they are. Most of them look like girls but Im not so sure. Here are some pics:

this is what we think a Rhode Island White chickens, which we also think is a girl

This is a Production red

A Dominique

and lastly this is a Blue/SplashAmericuana
Did I get the breeds? Are they boys or girls? (Btw they are about 17 weeks old)

If 17 weeks old I'd agree all pullets.
First one is not a RI white.

All pullets.

I don’t believe your Ameraucana is pure. It appears to have green legs.

And your “Dominique” has a single comb.

Then what do you think it is?

Then what do you think it is?

Looks like an EE or hatchery "hybrid".

I agree with what has been said!
