Auskan- My experience level is far below most of the good herpers people on here, trust me.
I have had one clutch and let me tell you, baby corns do in fact bite. Adults rarely do from what I have seen but those babies, they won't hesistate. One was even able to draw a tiny tiny bit of blood from me before it had been alive a full month. I have noticed pet store animals bite less though. Either because they aren't the greatest health, or because people have been constantly holding them during their stay at the store.
