A lot of us feed something like Purina Flockraiser which is designed for mixed poultry flocks ( chickens, ducks, geese, etc of all ages) and serve up oyster shell on the side for laying hens. You can also buy gamebird starter (non-medicated) and mix it 2:1 with scratch to achieve the proper protein ratio. And you need to offer oyster shell for calcium to your laying hens with that as well. My laying hens seem to enjoy this change of feed in the Spring when I switch my chicks from starter feed and move them out to the coop. Once the new chicks are laying then I switch back to the cheaper layer pellets for everyone for the remainder of the year, until I bring chicks out again next Spring.
