Since the picky hay subject has been brought up, I forgot and so has everyone else: Pitch the bale if you see droppings on it.
I had to throw out a perfectly good and very expensive bale of bermuda hay because the droppings on it were either Raccoon or Opossum.
While it looked like Raccoon droppings, I swear I caught something light colored skitter under the pallet a few weeks before I found the droppings. Light color means Opossum and Opossum MIGHT equal EPM if the opossum was a carrier
Mr. WTW said "I think you should just pick the manure off and feed it". I told him "there you go thinking again, if there's p**p, there's probably urine. If the critter has EPM my horses are dead. D-e-a-d dead and you'll wish you were"
Since archery was coming in and I was closing off the high ridge pasture anyway, I took the bale up there and scattered it. That section of pasture won't be re-opened until next year; by then the hay will be either eaten by deer or will have "returned to dust", so-to-speak.
