I kept a great colony for 3 years or so. I kept them in a plastic cake cover. When I split the colony for my step-mom, mine all died. It was weird. I liked using the cardboard inserts from Digorno pizzas as layers. It made it really easy to get a handfill at a time. I was feeding several reptiles, some frogs, and my skunk. Supposedly, my lory would eat them, but she just looked at me like I was nuts, and screamed until I got them out of there! It was about the time I started with chickens that I lost them.
