My pullet started laying a little over a month ago. She was 24 weeks to the day on the first day she laid. She laid pretty much every day with the random day off, but never more than one day between eggs. I had posted a little over a week ago that her last four eggs were getting smaller and lighter in color. Her last egg was pure white (she's a buff orp). I haven't gotten a single egg from her since that white egg. It's been seven days. Everyone else is laying steadily. They are on artificial light to bring them to just over 14 hours. There is no sign of mites or worms. She is acting normally. The only potential stress may have been my covering their run with plastic, but no one seemed stressed about it. Should I be worrying about her?
