Using a Pearson's square I've come up with a feed mixture and I'm wondering if it will actually work out. I designed it to fit the needs of laying hens, and it's under a 50 pound batch size. 37.5 pounds of corn to 12.5 pounds of cotton seed meal. With a scoop of oyster shells mixed in every time I feed them. Would this be enough to sustain them? I free range them so they could get other nutrients from outside.
