As your friendly neighborhood person with knowledge about food and cooking, 2 pounds is an absurd weight for an uncooked rotisserie chicken, that is a very small and cooked weight, 4-6 pounds is going to be typical. Also, more importantly, you cannot cook something faster by increasing the temperature past a pretty quick point, meat is an excellent insulator. No slap can cook the inside of a frozen chicken unless the entire chicken disintegrates.

Also, if you cooked it to 400 degrees it would be disguising. You just need to cook it to 165. This guy might know about physics but he has never cooked anything before.
