When is it safe to set fire to a bonfire that's been gathering all
winter without risk of it still being a home to a hedgehog? It's rather
big to move.

Light the bonfire in a different place and feed the new bonfire from the old
heap, I don't think it's wise to build a huge heap then set light to it, you
do not know how quickly, or slowly, it will burn, apart from the problem of
any animals which may have taken up residence.
