I have been feeding my laying hens 20% all flock feed. They seem to like it and are laying eggs very well right into winter. I am in Michigan were it gets quite cold. I have 21 hens and am getting 19-21 eggs a day - nearly full production. I do pamper them by giving them a treat every day in addition to their feed. Does any body else have an opinion on or experience using 20% protein all flock feed for their laying hens?
