I totally agree with brandon. To me the easiest feeder to breed is roaches followed by silkworms. My silkie and roach colony are pretty much left alone except for feeding. Silkies dont take up hardly any room. My roaches are in a 29g aquarium hidden in a closet. You should definetly check into a roach colony.....
don't climb, don't fly, run slow.... if they escape, it's probably cause you let them escape. load up the feeding dish, dont drop any while you do it, and you should be fine, i have not had a single escape that was not my fault.
The only time I have ever had some get out, is when I was sorting them and a baby would manage to get shaken out of the bin. They are easy to catch though.
