If you look close you can see that almost every single elk in the heard is limping and some are only walking on 3 out there 4 legs. I hunted that area for about 20 years and i have noticed that more and more elk are getting this, last year was the first year i have seen it first hand from a elk that we shot. Also there have been some studies on this and the way the elk are walking is a for sure sign that they have hoof rot!!!
