On the hay issue I have always fed qood quality hay so thats not an issue but like some people have mentioned some horses including my own won't eat all the hay you give them. If I give more the waste becomes more!!!
I would happily put more hay in their yards if they would eat it. So giving ad lib hay isnt always the solution.
I agree with Caroline when mine need weight put on out comes the copra, speedi beat, lupins and rice bran. Not all at once mind you
