I have an eight week old foal that was orphaned. I have been feeding him Foal Lac and giving him just a small handfull of sweet feed. The last few days he has not wanted to drink his milk, he just wants the sweet feed. I have no idea how much sweet feed to give him or at what age he can do without milk and just eat feed. I also keep fresh hay out for him and he eats a little of that every day. I do not want him to founder. He is not out in a pasture, he is in a pen. Any advice would be greatly appreciated.
