I feed my snakes in separate areas as well. One drawback to this is that we condition them to expect a meal through routine. (this even happens when you handle them often. If hes hungry, he will assume you are reaching in to feed him) What I do is use a glove when I take them out to feed. First, the glove is cooler than my hand, which reduces the chance of a feeding response. Second, the snake will associate the glove with food, instead of my scent. Lastly, if you are bitten, it won't hurt!!!lol. Be that as it may, we all get bitten, so consider yourself initiated into the herp world! Conrats!!!!
Really, the main reason I do this, is so that the snake doesn't bite the wrong thing, and risk injury to itself. (I know when I get bitten, my natural reaction is to pull away. BPs have delicate teeth, and my #1 priority is to keep my animals from being injured)
Hope this helps!
