I don't really know because I have only ever had the ladies I have now (plus Scary RIP) so I don't know how to compare.
They certainly fly a lot and are always in rapid motion until they nap when the fluff up like big balls and bury their heads in the fluff. They definitely run around faster than the others but that may be because they have to do so in order to avoid being pecked by everyone else.
They aren't very cuddly but none of mine are really cuddly, and I can grab them if I need to pick them up to examine them.
They are friendly and are always under my feet when I am in the Chicken Palace.
They are much less assertive and in my face than Maggie is (she is a loud-mouthed RIR) but one of them has a thing about my ankles she pecks me on the ankle all the time.
So I don't know if that adds up to flighty. They are completely adorable and I wouldn't have them any other way!
