Our Australorp Tweety laid her first egg last Thursday (yeah!!!!). It was actually very large so we were thinking maybe we missed a pullet egg or two. Since then, there has been nothing. She is currently our only layer and is in her own run right now, so I know we didn't miss anything since then. Is 6 days or longer between eggs normal? She is acting fine, eating, talking, etc. At what point do I have to take action? Thank you for any insight.
