I'm stumped! Calling all brahma bantam experts!

[HERSHORTNESS]

The dark brahma on the bottom of roost I was thinking is a roo? Is there any way to know at 7 weeks old going on 8 weeks? Would they be done with the juvenile molt to know if the penciling is going to stay or not? I also have a dark brahma on the top row in the back. The coloring is a little lighter. But I didn't have good updates pictures of that one yet. Any help would be appreciated.

Definitely a pullet. Dark brahma males look nothing like the females.
