Now, let me play the devil's advocate here... First, let it be said that i think chickens benefit greatly from being able to free range... and access to all the white clover and any other plant they will eat... except for my garden... is a wonderful thing for them, for my yard, and for my wallet. Now, here comes the devil's advocate part: IF a lot of plants are high in calcium, and it is better absorbed than the minerals in the layer ration... and if chicks obviously crave those high calcium plants, why are we so greatly concerned about not letting them have layer ration? Could it be that calcium is not really the chick enemy that we're told that it is, merely the delivery via solid mineral form, or perhaps it's not a problem at all. Follow up question: If our yards have such an abundance of free readily absorbed calcium, why are we (those of us who have free range available) spending money on chicken feed that has a pile of granite dust in it (or what ever the calcium supplement is)???
Last fall, after seeing the mineral sludge in every bucket of FF, i decided that i would no longer buy layer feed. My girls get supplemental oyster shells, as well as all egg shells fed back to them. I noticed that as soon as they had green forage available, they stopped consuming the oyster shells. A further little bunny trail for the brain to work on: If vegetative calcium is better absorbed than the mineral additive, why not supplement with sprouts or dried plant material in the winter?
Ok, back to our regularly scheduled programming.
