Yes I have egg cartons in there and damp cotton balls, but I think I need to just step up the size of their container. I was unaware that not enough space could lead them to do that. Good to know, it seems if it's not one thing it's the other!

Is there a rule of thumb for the size of the container per amount of cricket?
If so that would be a huge help
I keep about 3 dozen crickets at a time, so what would be a suitable sized container for them? I'm using a standard critter keeper now, but it looks like I need to go up my game!

Thanks again for the info guys!
