It's likely that they all aren't ready to produce eggs, and also likely that nobody is laying an egg each day.
Patience! It's hard, and the pullets will do what they do...

Welcome!
Could there be a hidden nest somewhere? If they are out, maybe.
An egg eater, or nest robber getting into the coop?
Shortening daylight hours can affect laying, sometimes even this early in the season, or they are just pausing to make you crazy.
