What's the volume of the chicken/sweet potato you are feeding him?

I don't think most baby food is a good choice, short of just a one time feeding. It is very high in vitamin A, and chicken is the wrong kind of protein for a dragon and can lead to gout in the future.

The best choice is Critical Care for Herbivores from Oxbow. Dragons prefer the Anise flavor. Mix it with half water and half ensure vanilla. Use more liquid than what the directions instruct.

Most vet offices sell it or you can get it here:

I've had vet techs. says dragons should eat the carnivore formula but that is incorrect.
