When nature decides to leave the helmets on mine, it's intent is almost always to kill anyway! Three out of four times I end up with a stuck helmet it never comes off and the poor little thing eventually dies. Usually I give them a little time before attempting to remove the helmet myself but if it doesn't budge by itself after a few days, I take the risk of removal. The other thing is, the ones that do manage to ditch the helmet by themselves can end up far too leggy if the helmet has been stuck for a prolonged period of time. (I left one on recently that ended up growing 10cm (4") before it finally carked it!)
I dunno, these days I sow extra seeds anyway to allow for some fatalities.
