I ordered a fantastic chicken coop and the contractor will be here next week to attach a large pen w/roof for my 6 RIR's layer hens. I started looking on this forum as to what feed is best for my girls and now thoroughly confused. So far I have read that people use Blue Seal, Purina Layena, and Dumor. Seeing that some have had issues with smell and waste I was hoping that someone could point me in the right direction. My girls should be laying by next week. I have also been told to mix in scratch an oyster shell with the food. Any help would be greatly appreciated!!
