Hi there, We bought young chickens last spring and got eggs all summer. Moved them to a warm spot for the winter and they continued to produce...until now. They now look messy and aren't producing. Is this that molting thing I've heard about? Could someone explain the process of molting to me? Do they have to molt to keep producing? How often do they need to molt? When is the best time to molt them? How long does it take? Do they do it by themselves like mine are appearing to do? Do you need to do anything during the process like change their feed, the temp, the lighting? Could poor conditions such as bad ventilation or not enough natural light cause molting? I wonder if mine are just sick as they are indoors with no windows. A light goes on and off about every 12 hours. Please assume I know nothing about chickens. I tried to google it, but don't have time to read and read so I figured I'd just ask. Thanks! One more question... How old do chickens lay until?
