Thanks to everyone for the help....been hoping between the different pages, my hens have a very large area that they scratch around in and I am sure they are probably getting some "grit" there. Have not gotten the Oyster Shell yet, but I will next run to a feed store. I did get yesterday the 20% Protein for layers feed from Kings feed and mixed it in with the remaining feed that I had left. Hoping that by Saturday my hens will go off strike but getting all this other stuff lined up also. They have pretty much taken all the grass in their area so was wondering if I should throw in some leaves. My horses have alfalfa and I was thinking of shaking some in their run, but saw Alfalfa as a poisonous plant so curious there.
