Our babies are NOT outside yet, so they are not getting any grit (can't find anything that doesn't have Oyster shell in it) right now. They are still in the brooder which is getting smaller everyday. So, what snacks besides eggs and yogurt can they have WITHOUT grit?? I was thinking maybe some strawberries or biscuits or something along that line. But what else. I did look a the list of items they can have, but it really doesn't say which one REQUIRE grit.
