MICO-SPAR CUBICAL GRIT?
Mico-Spar Cubical Grit is a hard mineral product containing sodium, aluminum, magnesium, lime and iron, natural chemical properties which every poultry raiser knows are necessary to produce paying hens.
Paying hens lay their share of eggs regularly and willingly, never needing to be "forced" because they are well and strong. These are the slow but sure kind, the kind that helps raise the mortgage.
Mico-Spar Cubical Grit produces this kind of paying hens because it makes and keeps hens healthy. It creates perfect digestion because it keeps things in the crop on the move, owing to the fact that the corners of the cube always remain sharp. Honest, practical tests have shown that Mico Spar Cubical Grit is the hen's choice, and that the minutest cube left in the crop retains its sharp corners.
Mico-Spar Cubical Grit is not a hen food or powder. Its use is to tone naturally the entire system. It is an economical Grit because it does not crush in handling, because its bright shining surface in the scratching pen attracts the hen, thereby preventing loss, and because no oyster shells are needed.
If you are a hen raiser put Mico-Spar Cubical Grit on the hen yard menu and you will prove that Mico Spar Cubical Grit is worth crowing over.
