I have only ever fed these girls manna pro's organic layer feed. My girls are anywhere from 22-28 weeks old. I have 4 red stars, a delaware mix, columbian wyandotte, and two barred rocks. I have yet to see an egg. I am starting to wonder if I should try another feed? I feed them the manna organic layer feed, scratch is a mix of red wheat berries, BOSS, millet, corn. I have free choice grit and shells in coop. Water available 24/7. They get sparing scraps of greens, and range a bit. Only one girl has a comb that looks really ready. What is everyone's experience with manna pro organic layer feed and production?
