Glad to hear your snake is eating well for you. Looks like she is still a baby since she is eating rat pinks. When she gets older she might get a little more skittish of her surroundings and may be a little freaked out when removed from her enclosure. If it ever becomes a problem I would suggest feeding in her enclosure. You can put the prekilled rodent on a paper plate so she doesnt injest susbstrate if you are worried.
I feed about 60 BP's a week in there enclosures. Some could care less where they eat but most are very skittish and wouldnt do well if removed. If it ever becomes a problem it is definately something to consider.
In the wild BP's are most vulnerable when eating/swallowing so they like to feel secure.
In many cases the need for security is stronger than the need to eat.
The two main reasons a ball wont eat is tempreture and security.
Just something to keep in mind if you should ever experience a feeding problem.
