I don't know how I grabbed the wrong bag, but I don't have any chick starter left and the new bag I bought is Egg layer. I can't make it back to a feed store for at least a week. The only other options I have other than the egg layer is some regular eggs, "garden treasure" wild bird food, and some 'ol roy dog food. The egg layer is 3-4 % calcium. The wild bird food says the feed contains calcium but I can't find a percentage. The dog food is 1% calcium.
