Calf Manna is the BOMB! I haven't seen an egg since late September/early October. I wasn't worried, just figured molting & winter had them on break. I had already been giving them snacks of BOSS and meal worms to help with feather making, and I saw on here that someone suggested Calf Manna. We always used it for our lambs, so I was familiar with it. Anyway, three days after starting up giving them a handful or two of Calf Manna every day, and we are back in the egg producung business (well THEY are )! Great stuff!
