You can, but you can't feed them like you do crickets. They will happily gobble a bunch, then a bunch more and may then vomit them up. You can try 4-5 at a time to begin with....or do 3-4 in the a.m, then later around 5 p.m..Be aware too, that beardies are all different, and once they eat supers, some may not go for crix as easily, but will hold out for the supers. Your dragon should be eating greens as well. If he's not, then crix are a better staple because they can be gut-loaded better than supers. Sooooo,it's better to wait until he's just a BIT bigger, even an inch.
