I have four chickens, all a little over a year old. They've been laying like champs for the past year, and layed all through last winter. One of them started molting a few weeks ago, so I've not been expecting her to lay. Her feathers have grown back in, but her comb is still very small. But why did the other three stop laying too? They have no sign of molting. I usually let them out in the yard for a couple hours a day, so I thought maybe they were laying in the yard somewhere, but I checked everywhere (Its a small yard) and there is no sign of eggs. Finally I kept them confined to their coop and run for 24 hours and did get one egg, but that's it. Is it just because the days are shorter now? We are getting a little less than 12 hours of light right now. Why would it be different than last winter?
