Need some help. I have about 25 hens that are only laying about 3 or 4 eggs a day. They have clean water all the time. They may 18% lay crumble with 3 different types of herbs mixed in. They are on 17 hours of light. They get works and scratch as a treat. With all that I still only get 3 or 4 eggs. What else can I do to increase egg production. They also have clean nest boxes. Please help
