I would guess this is a little less important with corns than with BPs since they tend to have less feeding issues. Is a corn that has had 1 or 2 meals "well started" enough to be pretty safe? I have no experience with teeny tiny hatchlings. Our BP was "6 to 8 weeks old" according to the breeder when we got her, and the corn was at least 4 months old (based on her being an '07 that we bought in April '08).
