I had a chuck that I was having trouble acclimating too. One thing I read on this forum during that period was to cover the sides of the tank with something opaque so that the chuck didn't feel so exposed. I think that this helped a lot in terms of making her feel comfortable eating. My wild caught Gracie's three favorite foods are: nasturium leaves and flowers, dandelion flowers, and wild raddish flowers.
My wc won't eat any insects. But I got a cb baby last fall that came in pretty thin. It turned out that he loved waxworms and mealworms and using generous amounts of these along with the veggies enabled him to get back to a good weight in 2 weeks.
Do you have a good UV light? They can do wonders. I love the T-rex mercury vapor bulbs. I was recently talking to one of my friends who takes care of her college's herp room. They've got an old chuck and she bought him one of the mercury vapor lamps. With that light, he shed his tail skin for the first time in at least 5 years, and went from a drab gray to vibrant black and yellow.
Also get lots of rocks, but make sure that they won't shift. My chucks really seem to like squeezing between two of them. I think that the tight squeeze makes them feel secure.
When you make the salad, leave the flowers whole and count how many you put in, this will let you know if your guy's eating. You should also fill the bowl with water and mist the salad. This keeps the salad moist and will help get him hydrated.
Also initially my wc would not eat anything if I sprinkled supplements on them. Now she'll eat things that I put the sandfire superfood's iguana dust on. It might be best to hold off supplements until you can get him eating.
If you can get him eating, they can recover really fast. Here's my cb baby when I got him at a skinny 14 grams, and two weeks later almost completely recovered at 26 grams.


One more thing, how big is your baby? My wc was about 9" head to tail when I got her in August '04. I thought she was a hatchling from the previous season making her a yearling. It turns out that wild chucks grow slowly and she was actually likey 3-4 years old. I think this is part of the reason adapting to a tank was so difficult for her. She didn't seem to settle in until I upgraded to a 100 gallon. If yours is in this size range, you might want to try a 60+ gallon tank if you can swing it, the bigger the better. Here's Gracie my wc the week I got her.
