I have a dozen hens and I'm only getting 2 eggs a day. Most days it's only 1. Sometimes I don't get any. They have a light that's only a timer and on during daylight hours. My concern is some of them have pale combs. Last year they were laying at least 4 or more eggs a day in the winter. They get fermented feed that is made with grower/finisher feed and BOSS. They get left overs as well. I think they are molting too. Any idea what else I can give them to help them?
