Chickens not laying

[Strategic Chicken]

Hi. My three buff Orpington hens are 24 weeks old and one of them laid their first egg one week ago. She laid another the following day, but hasn't laid a single egg since then. It has been seven days now, and I'm getting worried. It is my first time with chickens. Perhaps it's because of diet? Maybe because its winter? Maybe she is egg bound? Please help! Tha k you.

They're still young, be patient! New layers don't lay regularly.
She'd be dead if it was egg binding and unless her diet is very poor, it won't be that. High protein layer is recommended, I use game bird layer or nutrena egg producer. or chick grower with oyster shell on the side. The 16% protein layer simply isn't enough for your dual purpose layers.
