Just saw this comment,
In the past i use to take my ball python out and transfer her to another enclosure for feeding. Mainly for view purposes, and the myth that if you feed them in another enclosure they are less prone to bite. I say myth because i don't know how this could be proven or become a FACTUAL theory.
NOW! My snake has grown soooo much and transferring her to another container is really just not an option.
My advice to you is to just follow basic handling guidelines and you will avoid being bit. With that noted, i would say feed your snake within the enclosure. For two major reasons, one being that the least disturbance to the snake is ideal for preventing regeneration. Secondly, not saying it will happen but, my snake has been very defensive when it comes to her meals. If she sense more heat around her after she lets go of her freshly strangled prey, if she does not feel safe she will telescope up and defend her meal.
So really the choice is up to you but i really don't see that many pros to feeding your snake in an alternate enclosure. Its easier on the snake to just receive its meal within its enclosure were it feels safe. Then it can relax for 24 hours in which it then can be handled by you again.
Sloppy post but i think you will get the idea.
