due the biblical rains we have had, our loading road(mud hole) is a mess. We have more rain today and tonite. The cattle are almost impossible to get to the chute right now. It is time to worm and I cant get them up for the Pour on. Have any of you had any luck with the blocks. I know it may not be the best but should i wait till i can get them in the chute or use the blocks. Does it also get mites/lice or only internal. Any info will be appreciated
