You could roll the bucket around to loosen the soil and gently remove the crown to see what you have. If it has produced any rhizomes over the course of last year, go ahead and lop one off for your friends. If not, just put it back in the bucket and wait 'till next year. I lifted some yesterday that were planted last june and separated the 1 year old crowns (there were about 4 rhizomes per hill) to give to the neighbor. They developed into beautiful little crowns but hadn't produced any rhizomes as of yet. Still, it's great to see what can happen over the span of one growing season.
