Thanks everyone! This is so helpful!
Kind of disappointed about the barred rocks, I liked the balance they struck between being practical (egg-layers) and fun/friendly. But if they are aggressive to other birds that won't do, as I'm pretty sure I want to start out with a mixed flock, at least until we decide what our favorites are.
I don't care if the Wyandottes are aloof as long they don't hurt the other hens. It'd be great if there were some friendly/approachable birds in the flock too, especially while my boys are young.
So, it seems like the Orpingtons, Brahmas, EE would be okay in a flock, with Wyandottes generally being aloof (and occasionally aggressive), and barred rocks maybe too assertive for the gentle breeds.
I haven't had any problems keeping a Wyandotte and the Orps together, they basically ignore each other (opposite ends of the pecking order or something).
Also the approachability of the birds depends a lot on how much daily time you spend with them, talking to them and giving them treats and stuff like that. I'm sure you could tame down some of the more aloof or flighty breeds, it would just take more effort than with the friendly/relaxed/curious breeds like Orpington, Sussex, and EEs.
The only layer chicken breeds I've ever heard aggression towards other chickens associated with are leghorns, Rhode Island Reds (who have a particularly bad rap for that), and New Hampshire Reds.
