Will live feeding switch my BP over from F/T?

[John1982]

some people are telling me to not feed her live because it will be really difficult to get her switched back over to frozen thawed

Preference depend on the individual snake. Some have no problems switching between f/t, prekilled, live, or even different prey types. Other snakes might get hung up on something specific once they get a taste. There's really no way to know for sure but those with super strong feeding responses tend to be the least likely to imprint.
