If you cant convert them now (it requires tough love (of course given your BP are healthy and have a good body weight)
I convert mine back and forth each year ..let me explain.
I produce my own feeder rats and mice and prefer to feed live (with over 50 snakes it is just more convenient for me) however during the winter months I always end up producing more then I need as my snake slowly go off feed for months, so I euthanize the feeders, freeze them and once my snake resume feeding they are offered F/T first while supply last and then back to live.
I am doing that every year and trust me when a snake comes out of several months of fast (especially females that have laid) they will eat about anything.
So is it worth it well F/T has it's advantages and inconvenience what matters is that you feed what works for your snake and is convenient to you (one is no better then the other)
