Today was about 70 degrees here in Colorado. Can the chicks be outside for too long? Mine are mostly pushing 3 weeks old. Is there a chance that they will fill up on lower quality foods that will stunt their growth or that their bodies can't digest yet? When I hand feed them after they've been out, they get all excited at first from my little "chick, chick, chick" call, but only a handful of them really get excited about the treat. Normally, they go nuts and devour whatever I offer them if they've been confined all day.
