More questions about feeding my little peepers. Grit: What size is best for young poults, and when should I start adding it to the feed? I have sandy soil; can I just scoop up some coarse dirt and let them pick through that? Grass: I have some clover and orchard-mix growing here; when can I start giving that to the poults? Bugs: Can I let them have insects collected from the garden (earwigs, sowbugs, etc.), or is there a risk of disease?
