Another person worth talking to is Dr. Jarchow at Orange Grove Animal Hospital:

He does the herp vet work at Reid Park Zoo and for the Desert Museum, and I know he has a whole backyard full of hard-luck tortoises that are either injured, or in rehabilitation, or are otherwise too delicate for the tortoise adoption program.

If you have some money, it's worth taking the babies in for a check-up/ parasite check. He'll give you good advice.
