I've heard of dusters losing their heads but never personally have bad it happen. Other the whole double feather head and what looks to be about half an inch of the worm. Is that what it normally looks like? I picked it up and put it back in the tube for **** n giggles but watched it get pushed right back out again. Even the dropped head seems to still have some reaction when I touch it. Does this mean my worms dead or is it just rejuvenating a new head? Never actually seen a dropped head to compare it to...
