Well first bit of advice is make sure you're not trying to feed back to back to back- if they don't eat wait about 7-10 days and try again because otherwise you may just be stressing them out more. I would work hard to get that humidity down as many times refusal to eat is caused by a) settling into a new environment b) too hot c) too cold d) humidity too high e) humidity too low. It's pretty crazy huh haha. Anyways yeah I 'd double and triple check husbandry stuff and wait a while before trying again- they have to get settled in before they eat. I didn't give my snake time to settle in before I first fed and it resulted in him appearing scared of the f/t mouse as well, I waited about eight days and tried again and he fed. During that 8 days I just left him totally alone aside from changing water in the morning I just let him be. Others on this forum know a LOT more than I but that's just some stuff I've picked up on I really hope they get feeding for you and I think that they will.
