Hmmmm.... I guess I'll look up the manure next time I go there. I always just pick without looking.
What SR said.
My vet had an article about it in their newsletter thing a few years back. Next time they were out they showed me how to do it.
She used one of those long gloves they use for rectal exams. Put a manure ball in added water, agitated until it was all dissolved. Then tied a knot in it and hung it on the stall wall until we were done with shots. By then everything had settled into the fingers so it was easy to see fiber bits vs dirt/sand.
