I need to know how I can increase the production of my eggs. I buy 50 lbs. of cracked corn and 50 lbs.of laying crumbles every week. We have 15 big hens and 37 smaller ones that aren't laying yet. We also have 8 hens that are just startiny to lay.We get maybe 10 eggs a day.we were getting 15 at one time. There must be a way to increase production.
