We have a surprise rooster in the flock now, so I'm going to be feeding a multi flock with the oyster shell for the hens. The multi flock is so much more than the layer feed! At my local Tractor Supply I have the option of Blue Seal Multi flock for $22.49 or Purina multi flock for $17.49. We have always fed Blue Seal because the general consensus was that it was a better quality. The price difference is tempting though. Is the quality difference worth price difference? Is there a cheaper option than multiflock when you have a rooster? I've tried local mills but no one has a multiflock, it's all layer mash, and the mash doesn't even work well in our feeders anyway.
