Glad to hear your corn is eating well for you again.
Not to start any debate over live vs f/t vs p/k but a lot of the "live feeding is the debil" stuff is really internet hype. Yes live feeding done incorrectly but a snake owner that is either inept, inattentive or simply didn't bother to learn to feed live correctly or never understood the predator/prey dynamic can be very dangerous for your snake. Done correctly and for the right reasons, it's a perfectly acceptable feeding method. I've been live feeding snakes for a few years now - boas, milksnake, ball pythons - everything from hatchlings to big adults. If it was that dangerous somehow I doubt I'd have all these healthing snakes hanging around waiting for dinner LOL. This is not a "you must feed live" thing. It's just my own experience.
Feed what works for you and most importantly for your snake. Know the methods of that feeding style, know the prey, know your snake - all the rest of what people say is just noise sometimes.
