Lots of times tongue issues are associated with low calcium from what I've read from some of the experienced keepers on here. I don't know if that is the problem in your case since you are dusting the feeders. I had a litter of 3 baby Jacksons born this past December, and the only female of the group had a difficult time with ter tongue. It got to the point whrere she couldn't use it at all. I had to moisten my fingertip so that a cricket or tiny mealworm would stick to it and let her chew it off my finger. I had to do this for about a month and she finally came around and started to use her tongue. She still isn't completely up to par, but she is growing and getting better. I made sure to gutload her crickets specially with turnip greens and a straight powder form of spirulina (lots of good vegetable protein). I don't know if any of that is relevent, but she seemed to bounce back so it's worth a try. Although, if she is keeping her eyes closed alot during the day, at her size, I would think there might not be too much hope. Hate to sound pessimistic, but she is very small. I hope for the best for her.
