Have you noticed feathers around the pen? They could be molting or maybe there is some sort of parasite.Question for you. Have 12 hens that are less than a year, and we're laying machines from 20 weeks on. My barred rocks hen went broody, and all hens stopped laying ever since. Is this common? I add artifical light since the change in season happened about the same time. Could the broody hen be the cause for the egg strike?
