about chick grit, I just take my regular grit and put it through a sieve to get the smaller particles.As long it is chick grit, yes you should be able to feed most anything. Be warned about hard things to break apart. Meat should be somewhat finely chopped, no bigger than a pea. I had the unfortunate learning lesson of a 9 week old Silkie getting a blocked intestinal tract from a piece of meat she gobbled down. Even with grit she couldn't break it apart inside.
