I started raising whitetails in 1996, through the years we have lost a deer or two here and there to EHD. I hope what happened last year was like a 100 year flood,we lost half of our herd, like Wayne said, some of the animals were fine one minute and dead the next. Deer were coming up to the feeder and acting perfectly normal then falling over and going into thier death throws---it was unreal. Not all of them died this quickly, some lingered on for a few days. Hopefully we wont need it this year, but I will sure give it a try if it hits us again.
