My hens have gone from a completely indoor coop to a free range from 7am to dark, then chicken tractor at night situation about 1 month ago. Within the last few weeks they are eating less and less of the layer ration in the chicken tractor that was always their staple in the barn. But, I'm getting even more eggs than before (they faithfully come back during the day to lay) and they look and act great. My 2.5 yr old Golden Comet went from 3 eggs a week to 6! They do have free access to grit and oyster shell in the tractor. Has anyone else seen this with their hens?
