I really think the grit issue should be related to the type of soil you have. Grit is ground granite, a very hard stone. If you have anything comparable in your soil, then you shouldn't need to supply it. And there has been some research that suggests some hens need more calcium than others.
A small bag of grit and oyster shell probably costs about $15 together. I don't know the exact price because, even though I offer both, I haven't run out in nearly two years. I have 17 chickens, and have had a good number more.
