I hope this doesn't sound TOO dumb. I can't figure out what to offer grit and shell in. The girls don't need it yet, they're only8 weeks old, but I wan't to be prepared. We're going to start letting them out in their yard today or tomorrow. I know they'll pick up sand & gravel there, but will it be enough if they're not outside everyday? Please don't tell me "just any container they can't tip over" - I'm new and clueless. We thought about a quart jar chick feeder, but my daughter taught Princess to jump up on it so that my daughter could pick her up and hold her with out falling into their baby crate. Now, the big girls like to sit on the feeders! Thanks for your input and letting me ramble. I have to go out, so I'll check back later.
