I have a question - do ashes keep down external parasites? Last summer after our goats had trimmed the tree line of every tree we would trim the tree around the property to give them some yummy stuff to munch on (this in addition to their regular feed). Well, as you can imagine the dead tree limbs piled up so we had a bonfire. The goats LOVE to roll and lay in the ashes that were left by the bonfire and as of yet I have not seen a single external critter on them with the exception of the occasional fly. Do ya'll think the ashes kept fleas/lice away?
