dominique pullet or roo

[Chickenjoe23]

I have three barred rocks which I think are all roos because of their yellow feet but my six dominque chicks I think five are pullets but one has got me questioning it because is feet are mostly yellow, way more yellow than the rest and the dot on its head is very small with a light gray patch around the back of the neck. I will try to get a pic of it later when I get home

I need help deciding what they are

A pic would help
