I went in there today to get one out for a treat and the worms had broken into big shelled black bugs WHAT THE HELL ??? There skin is broken open like a snake skin and these black bugs are now in there .... worms turn into this ???? and I cant feed my cham this even though it was worms for a cham :s .... ???
