I thought chickens need fourteen hours of light to lay. I got the first egg from my Barred Plymouth Rocks today. The hen house is not heated and does not have a light set up for extra hours. Here in central Pennsylvania we are like most everyone near the shortest day light hours of the year. Was this a freak mishap? Or can I expected the eggs to start flowing on a daily basis? I have to work during week days so I guess frozen eggs could be a problem?
