Getting first baby chicks in a few weeks, and I'm learning and planning ahead on how to raise them. I can't free-range them because of my yard size, but I wondered about supplementing their regular feed diet with various green veggies from the store. Maybe sounds crazy, but if I toss in some collards, chards, kale, etc, into their run each day, will that give them meaningful nutrition that would make their eggs healthier and a brighter orange yoke? I know they won't have the benefit of yard bugs, but I wondered about the benefits of a good handful of leafy greens. thanks.
