Hey Bob:
I'm really glad things are working out for your lizards. Now I can sleep at nights (just kidding).
Since the individuals you have are bigger than babies already they may be close to full grown within a year. Once they start utilizing all their food instead of playing "catch-up" you should notice significant growth within the group. You had a nice group of animals to start with and that always helps.
Keep good notes and take lots of pics. This stuff will all be usable down the road.
Keep us updated on their progress. I for one am very interested in how they fare growing up. Maybe this summer I'll find some and begin working with them again.
Have a Great Day!!!
