We did not loose any cuttings to rain. We did loose our first, because a neighboring farmer accidentally had his spray, drift on to the alfalfa. It did not kill the alfalfa, but we won't know till this year if it had any lasting affect. We raise natural freezer beef, so we did not want to feed contaminated hay.
Not organic, keep the EPA and FDA out of your hair, we did that when the organic craze took off in the late 90's.
A hint, feed them some clean bread with the hay, saves on the grain and is packed with grains and surgar anyways.
