I have one little red leghorn that is supposed to be a pullet... she is the most spastic little sucker you've ever met. I stick my hand in the brooder and she sprints over to me (which to me reads roo, because "she" will run toward weird noises too like if you scratch the side of the brooder). What's the deal? Are leghorns always this sketchy? She also is not really feathering out like the rest of my flock. They're supposedly the same age but my buff chants and BR's are way more advanced than she is and she pecks everything that moves (and even things that dont!).
