I would switch to nice hoppers now if I were you, I'm going through the same thing and have offered rat pinks and rat pups but some just don't go for the rats right off the bat so now I'm switching to mice to see if it will get their feeding response strong again. I hope you can get them eating though, I know it's really stressful when young ones don't eat.
