when my babies were 2 days old i went outside and got a small dish of dirt and gravel. i nuked it for 2 minutes to kill any bacteria. it was only a matter of days before they outgrew the small dish. about 3 days ago i filled a shallow horse feeding bowl (you could use a rubbermaid or cat litter pan) with dirt and leaves. they have been great, it gives them something to do, they get grit. remember living animals are not sterile, nor are they meant to live in a sterile environment. i vote start with a small dish of nuked, cooled sand/dirt and move them up.
