It has been a long time since I've had any snake (they weren't garters, btw) that would initially only feed in a small separate container & left overnight. But happily, they usually get a lot better after only a few meals taken that way, & started eating as they should- I hope yours all transition quickly. It's as if they suddenly realize "hey, food IS good!"Sounds like you have a lot of different personalities to contend with, but they're awfully cute, I gotta say.
