When I had my herd of Nigerian dwarf dairy goats I used their droppings all the time. never had any stay weeds pop up. But then I keep it in a pile and just used from it through out the year. I would add new and integrated it with the old and just kept using. I use to put the (what I called them) nanny berries in a large bottle and used it as fertilizer for my potted plants and veggies. Now I did rotational grazing with my herd.
Don't waste that wonderful source of fertilizer that is yours already.
