I believe the Nutrena brand has marigolds in it as well. I have a rooster so I feed All Flock. I have OS on the side. Also with home grown eggs is that you know the hens have a good quality of life.Store bought vs home grown. Y'all can figure out which is which. My chickens free range daily nearly all day and there is always something green for them to forage on with our weather. Their feed is Purina Layena pellets which has marigold extract in it.
