I attach two plastic one-quart freezer cartons on the sides of my coops. One's for oyster shells; the other is for grit.
I buy 50# bags of granite grit at my feed store for $9.61 and 50# bags of crushed oyster shells for $6.25. One bag of each should last me for several years.
Note: I am looking at a receipt for both that only show price, not items; the prices might be reversed for the two items, i.e., the granite grit might have been $6.25, and the oyster shells might have been $9.61. I'm not sure, but it seems like the grit would cost more.
I do not feed "layer" feed or put any oyster shells in the containers until AFTER one of the same-age hens has laid an egg (usually a soft shell). Excess calcium from the wrong feed or oyster shells in a young hen that hasn't begun laying can damage her body.
BTW - I also get large bags of egg shells from the manager of a local restaurant that sells breakfasts. I put those in a hot oven until they're very hot, take them out, put them in a bag, pound on and crush them into very small pieces. Then I mix them with the oyster shells when I fill the oyster shell container. Most McDonald's restaurant managers will save their egg shells for you, but wherever you have them save them, be SURE to pick them up at the time that you say you will; they have to deal with their local boards of health inspectors.
