Does the same rule apply to butterworms as to silkies concerning the size of the prey? And what do the butterworms need to eat? There was no info included...Also, (and this may sound really stupid) but is there any risk from a calcium overdose if my bearded dragon eats too many? And final question, I saw a website that said to keep the lid off of the worm container while they are in the fridge?? Thanks so much, Vanessa
