Petr Necas has a great video on over weight. He has a lot of videos so u will let you explore his fb page. Put his name in the search above. Well you have to realize if our chams were in the wild they would be putting on more miles climbing upnand down trees and bushes. In a cage, they are limited i imagine. I think i went wrong with the transition to an adult. So i over fed him for a few months when i should have been reducing. Now every other day for a while then every three days with a treat on day two. I have a female panther who is younger. She is now about a year so i can cut back. She loves crickets! Best little hunter ever and my male vieleds name is Hunter! She is putting him to shame. His weakness is wax worm treats. When they cacoon,i throw em in a plant so they are a moth when they hatch. Both. Will eat the moths! That way i have no waste. i have two cricket tubs. I try to put hatcglings in one and grown in the other. I find the more room the better and i covered the outside and bottom with foam i glued on added that heat incillating foil. I have both tubs on a heating pad on low. I feed them carrots and corn meal or wheat germ and have water pillows. also you can throw in apple and orange slices. But dont let the fruit rot as it turns to pure alcohol and they get drunk and die. To start, order 300 1/2 inch striped and 200 1/4 inch. The feeding starts from the 300 and i havw vermiculite as a subatrate and thw adult females will lay the eggs right in there or you can put a sandwhich size tuperware with 2-3 inches of moist soil i. A corner. Once the males start chirping you know they are mating. When that batch is gone.cover container with moist papertiwrl and put lid on tight then set on the corner of the heating pad. If its too hot, it will cook the eggs. You can put a towel under it if needed. Then once a week you peek. When you see little black specks on the paper towel, they are hatching. Dont change anything but add some water to a corner. Keep letting them hatch then take the top off in the tub with fresh vermiculite and apples, carrots and corn meal. Whn they get a bit bigger add paRsley. I make parsley trees which they strip bare. Then you can back off on gweting so many cri kets at petco. I order from rainbowmealworms.com. always fresh, good variety, and toy can trust shipping time. Omg i have to go. Its my sons birthdaym
