I have tried lots of salt licks over the years with Joe when he was alive and Storm, but neither really liked them and even Joe ignored his? Must not need any salt..............The only one they both went "mad" for was a field lick in a big tub, I cannot for the life of me remember the name, it was expensive and I only really bought it when Joe was restricted to a tiny paddock as I thought he might be missing out on something in his diet. They used to argue over it and race to get to it first thing, Storm trying hard to get her head under the fence at it.............Guessing it had something sweet in it...............
