I feed my hens laying pellets. It's balanced, so no supplementation is necessary. That said, I do occasionally give them treats...meal worms, horn worms from the garden, etc. On of their favorites is fresh yard clippings when we mow, or picked clover from the downhill side of their run. The only broken eggs we usually get are every once in a while, one gets broken against the marble eggs in the nest boxes...probably less than one a month.
