Hen or Roo? 14 week old mixed breed...

Lots of people keep bachelor groups with no issues.

My guy is living with a sebright cockerel and an unknown gendered silkie. They get along just fine, even with the huge difference in size, but each individual is going to be different. Mine is at the bottom of the pecking order in that group so he minds his own business.

So glad to hear this as the size difference worried me a bit, though this EE boy is very timid. The bantam chicks are about 10 weeks old and super tame raised-to-be-pets, even though they were hatched and raised by a broody outdoors daily handling since hatch has made them absolute love-bugs.

Easter Eggers are one of the aggressive breeds of birds.

Easter Eggers are one of the aggressive breeds of birds.

He is a mystery mix, no idea if he is an easter egger (carrying the blue gene). His mother was likely a Salmon Favorelle or possibly a Chocolate Bantam Orpington (though he seems a bit large for that).
I have heard some say EEs are very aggressive, but the ones I have had were quite sweet. In this case he is most likely a mix of more docile breeds.

Well, I guess it depends on how they're raised, good luck.
