Looking Like A Roo

This chick was one of four sapphire gems we got from a "pullet" bin at Rural King. Didn't know they were sex-linked until after we got them and I'm pretty sure this one is a roo, not a hen. The white dot on the head was less noticeable as a chick but it was there looking at pics from the day we got them. This one was clearly older than the rest but its also growing the fastest and has a heck of a peacomb for only being 2-3 weeks old. I'm not sure exactly how to spot barring on feathers and it may not have enough feathers to see barring yet.

Hoping it's one of the 10% of errors in sex linked chicks because we can't keep roosters in our city zone and this is the friendliest one. It's always the first to come to the brooder door and likes to chill next to me at the door or on my arm while the other 9 chicks are running around in the brooder. What do you guys think?
