To inject a little humor, and answer...

After eating 2 helpings of dinner on Thanksgiving, how much do you feel like running a marathon?

Your snake has just eaten something that is probably about 20% of its body weight. This is ENORMOUS. It's probably going to take several days to digest and the snake is not going to want to move around. Plus, corns tend to be most active at night and in the early morning.

What are the temperatures on the warm side? What are you using to heat it? What style of thermometer are you using to measure the temperature? Do you have anything to regulate the source of heat (make it hotter or cooler)?

The black thing in the eye is completely normal.
