All I found from my guys was a very small piece of the BP and a few tiny pieces of exo. They ate the rest. That is a cool idea, tho, if they don't eat them but from what I've read on this site I think most of the guys eat theirs.
I collect up the bits they don't eat, grind them into a powder in my pestle and mortar and then mix it into their food, so they do still get to eat it.
Wow, you guys are really on top of things! Saving one for emergencies is also a very good idea. How did you end up with an extra, though? Did someone not eat theirs? If that happens, what do you do?
