Cow proof protein block feeder

Rolling around an idea on a hanging type feeder that will hold 4 or 5 protein blocks that cows can't get to wondering if any one has experimented with the idea? Thanks for the in put Mike

Well you would have to put it too high for deer to put it too high for cows so in theory i don't see that working maybe some guy has a way but I've though about it alot and don't see a way just put the blocks inside a feed pen
