My gutload varies every week. I keep my crickets in an x-large kritter keeper (have about 1000 crickets at all times) I clean it regularly, I put a thin layer of Fluker's dry cricket feed that covers the bottom. Then I have Ectotherm cricket yummies in there which is gone in a few hours. Then I also put in, depending on the week, a bowl of finely chopped fruits and vegetables (apples, orange, bananas, tomatos, broccoli, lettuce, carrots, potatos, all that good stuff) which they eat like crazy. And I know they're gutloaded well, because all of my other reptiles eat the same crickets and they seem to shed normally and are fine. Maybe it's due to genetics? Species pushed beyond it's limits?
