I am not sure if you tried this not or yet, but it may be an option. I had one female hatchling this year that simply refused to eat. She skipped her first 5 meals in total i think. What worked like a charm though was a brained hopper. I used a sharp razor knife and made an incision on top of its head and spread it open slightly with the blade of the knife. I left it outside of her hide and it was gone 20 minutes later. She ended up never eating a live meal and was on fresh kill right from the beginning and eats fine now.
