hubby made me some large S hooks. I have 2 on the right side and 1 on the left. But I also have gentle La Mancha they don't seem interested in butting things around. I've not had a problem with them knocking it down but they will knock the minerals off the surface to get to the fresher minerals below that top layer. Is this what your goat is doing? Or is it your goat just wants to play?We use D hooks like people use on their keychains.
