Countrybum, re your question about what grit is--it is small gravel, etc, that chickens swallow and goes to their gizzard to grind up things they ate--they have no teeth to chew with. Free ranging chickens--and back in the old days--they picked this up off the ground, but with them in coops, brooders, etc, you have to provide it for them. It isn't expensive, and can be bought in a farm supply store, usually. There are at least 2 sizes--small, which is like coarse sand, and is for smaller chicks, and larger, for adult chickens. Like the above poster said, I would stick with chick starter till they are bigger. Not really good for them to give them all sorts of "treats" while really young--they need the nourishment provided by the chick starter. Just my opinion. Good Luck.
