I am getting ready to go pick up more Moorman's Mintrate blocks. I like the blocks except for how the cattle will roll it out on the ground. I have the block in the mineral feeder with the top that turns with the weather conditions, but they still continue to push it out. I thought about putting it in something a lot deeper or build a box with a lip around it that wouldn't let it roll over the edge, or putting up a plastic barrel and cutting a hole in it big enough for them to stick their heads in, and hang it on the wall. Does anyone have any luck with stopping this kind of waste?
