I would def get the humidity down a cople notches in to the 50% range babies have very sensitive skin early on and can blister or rot easily from to much moisture . A few tips that have work for me on finiky feeders 1: try feeding after the lights are out under dim light these snakes arent diurnal and tend to feed in the dark or dim light better 2: try both rats and mice ,many seem to have a preference for one or the other right out of the egg also try live and frozen 3: if nothing else seems to work you can try" braining" slitting the head open on a feeder for a little extra scent stimuli I have had good luck on stuborn feeders by useing a live mouse hopper and pricking its nose to draw a little blood , the scent and movement seems to really work well together any way I hope you get them all started off well
