I know. They are way overdue.
The problem with adding light is they will burn out more quickly. A chicken is born with as many eggs as it will ever produce. The more you coax them to lay these eggs by increasing their daylight in the winter, the quicker they will "run out". I'm sure you probably already know this, but I thought this was pretty interesting and worth mentioning for those that don't. I also read that coaxing them to lay more eggs is linked to reproductive cancer in young chickens.
Since I have no intention of butchering them when they no longer lay, I'm hoping the lead long healthy, egg laying lives, even if production drops to just a couple eggs a week.
But not getting their first egg is killing me
Not to mention all that crowing they do in the morning
