Can you please tell how much much a 3 month old hatchling should be eating? I put mine outside each day in a little pen, but it doesn't seem to be eating much. I also put various weeds/grasses from our yard in the habitat, supplemented with some romaine, but he doesn't eat much. Should I be concerned? I soak it daily and provide a UVB light when inside. The temp. in the habitat stays about 80 degrees on the warmer side. An info. will be greatly appreciated!
