Wiggling Cocoons means they are in good health. I have 20 of them I just put outside because I can't be bothered to raise them again right now.. I still have them in a container, not sure what to do with them, lol. I've wondered if it'd be OK to feed the cocoons to my frogs.. I really don't see why it wouldn't be. I actually kind of feel bad because they are going to waste..
