Is my 19 week old leghorns showing signs of egg laying

She makes loud noises and keep jumping in and out of the coop. She has been doing that for a couple days now. I do provide oyster shells separate but I'm not sure if she's pecking at it. Or should I not be to worried?

Forgot to mention she hasn't started laying yet!

Possibly she's getting close to lay, POL birds do get restless and you may find them messing with nests or kicking fake eggs around.

I wouldn't worry about the oyster shell since you said she's not laying yet.
