not per say bad to feed them in their tanks but sometimes the snake can confuse your hand for a snack and strike. so if you only have 2 ball pythons i suggest feeding them in a seperate tank or bin. however when you have a lot of snakes it becomes time consuming to feed them all in separte bins. personally i feed mine in their homes (then again i have over 10 snakes) but its not a bad idea to feed them in a seperate tank or bin.
