My two sheep mineral feeders floated away in the winter flood so I needed to get some more. A fellow handler, Norm had made a mineral feeder for another handler and I asked him if he could make me one. Norm made me one and it is great. It is better built than the two that floated away.
Here it is in my upper pasture. See how sturdy it is. It is quite heavy and even though the sheep brush against it, it will not move. The roof keeps the rain out of the mineral mix.
