I raise my own crickets and feed them Layena Gamebird crumbles for laying hens, which I grind to dust in a blender so the crix can eat it even when they are just hatched. I put two cups of crumbles into the blender and add five beta carotene capsules from a health food store. I grind about 25 pounds of crumbles at a time, mixing crumbles and capsules as above.
I end up with a bucket of cricket food that is rich in beta carotene and convenient to use. It lasts for weeks and the crickets get so much carotene their droppings are orange. I also note that when any of my crickets drown, such as when they are in a frog tank and don't get eaten in time, the crickets turn bright red like a cooked lobster. The same thing happens when wild grasshoppers and crickets drown.
Beta carotene brings up color in Collared Lizards and other animals as well. I once mentioned my interest in adding carotene-rich foods to my herp vet and he suggested offering small bits of Dandelion leaves to my vestigium. He said that Collared Lizards often eat bits of dandelion leaves when offered. He told me that Dandelion leaves are rich in carotene. I tried it and my vestigium's color popped within a few days. That lizard went from pale to vivid in no time.
On another note, here is a pic of a wild male Collared Lizard looking like a king. I love the yellow socks.



I also start all kids off on GREENS, carrots, they love them and grow to love them through adulthood. I have some that RUN to the side when they see the greens/ shredded carrots, coming.


Dang Joe why do things around YOU always BITE ???
