Feed him in the same enclosure. No need to move him to a seperate "feeding" enclosure.

Don't leave any live rodents in with him for longer than a few minutes without checking on them. If he obviously isn't going to eat, remove the rodent.

By the way, a 6 month old ball python should be around 5-600 grams and eating large weaned rats or small rats. A fuzzy isn't going to be much of a meal. Do you have any pics of Sid?
