Gender confusion in my brooder box....Help! (Pic Heavy)

[Blob Chicken]

All look like hens 'cept for the barred rock

I thought the BR looks like a roo; due to the coloring..


ETA:: I got the coloring mixed up; the white depicts pullets; more black depicts roos..sorry

so I change the answer to pullet...

BigDaddy'sGurl :

All girls. Especially the BR. She is very dark in the barring area and has thin legs with black wash down the front. If she is acting "roo-ish", it's probably because she is dominant. Very cute chicks!
