My girls are about 20 weeks old. I have dim light in the hen house all night. The chickens went through a molt before they even laid a single egg at which time they were about 15 weeks old, approximately. They hatched around Labor day weekend. I head out to the cop everyday hoping for that first wonderful egg.....nothing yet. How long should it take after a molt for the chickens to start laying for the first time. I also have a rooster. He is very "active" with his girls. I'm hoping that if he is any indication, the eggs will start showing up soon. Any input or advice is welcome. This is my first flock ever.
