I'm doing the exact same thing! I blended everything together so it was still quite thick. I had one girl who wouldn't touch her veggies, and our lactating female wasn't interested in her protein! Everyone's eating everything now and it's great. They seem to love it. I still give them a small amount of pellets, a few mealworms, and a small piece of solid food each night. But their bowls are empty every morning except the little pieces they spit back out so it's great.
What I did is a cup of calcium fortified orange juice, 1/2 cup frozen mixed berries, 1/2 a banana, 1/2 cup veggies (cucumber, carrot, zucchini, celery), 1 cup protein which consisted of some plain turkey, some plain yogurt, and some plain boiled chicken, a few squirts of honey, and a few pinches of protein powder. I think that was it. We froze it in an ice tray and give each glider a cube each night plus the pellets, mealworms, and usually we give a piece of solid fruit because it's what they're used to. It's great how everyone is eating all their food now!
Everyone here is saying to cut the pellets, but what that means is do not give them free choice of pellets, because they are mostly fillers. So you can have a fat glider who eats a lot of pellets and doesn't eat their actual food. That means they aren't getting nearly enough nutrients. I give each glider like 6 pellets a night. Not nearly enough to fill them up, but something to munch on. And it cleans their teeth. Actually now that I've mentioned that, our girl who wouldn't eat her veggies was the only one FINISHING her pellets every night. She probably preferred them and filled up on them and her fruit. So don't let that happen, just give a little bit of pellets each night.
