My mother hen is taking her 4 - 5 day old chicks out in the yard and feeding them all manner of things: grass, bugs, cucumber, scratch grain, dirt, random seeds and leaves, and not paying much attention to the chick feed I'm putting out for them. I would normally tend to think that mother critters know best.....but why are we given all these warnings when we try to raise chicks ourselves? There are so many things NOT to feed them or they might die, etc., etc.
