I have 11 girls, 4 are 2+ years, 3 are 1+ year, and the rest are last summer girls. I have put lcd christmas lights in the coop on a timer to suppliment their light. However they are not laying well. They get about 12 hrs of light a day, free range for 2 hrs, have unlimited feed access a day but I only get about 4 eggs a day. What am I doing wrong?????
