you'll always find conflicting solutions to keeping beeps; there's more than one way to cook a potato. what works for me may not work for you and vice versa. what's important is learning proper husbandry and coming up with your own solutions that work for you as well as the snake.
a glass enclosure is a PITA to maintain. for a first-time owner i have to recommend a tub: SUPER easy to maintain proper temps and humidity and babies thrive in them.
you can't say "live will not work for me" because this isn't about YOU. if your baby doesn't eat for 3 months and is losing weight, you might have to try live. this is the reality of owning a beep. what works for YOU might not work for the snake.
you can refreeze an unaccepted feeder and try to offer it a week later, but you can only refreeze a feeder once. where you toss it out is up to you. my backyard is a giant field so i'm lucky to toss unaccepted feeders over the fence and they're gone by morning.
feed in the enclosure. a separate feeding tub is counterproductive and stressful to the snake.
recommended enclosure: a tub, AP Cage once they're adult.
worldofballpythons.com is an excellent resource on morphs.
here's a video i watched to try and "prepare" me for the reality that i WILL be bit one day. the guy's calm demeanor and his talking to the viewers helped me realize it isn't so bad.
just to add: a THERMOSTAT will be the single most important piece of equipment you buy for the snake, and should be one of the first things you research and purchase. a thermostat is absolutely necessary, as is regulating ALL heat sources whether by thermostat or rheostat.
