I'd like to put my guy onto some sort of grain or pelletted feed now that it has started to get pretty cold here. I'd just like to add a few more callories to his diet. My vet has also suggested adding a couple supplements to his diet as well, but it is difficult to do this as he is currently only on grass and free-choice hay. I am looking for a feed that won't make him hot-headed as this is already an issue as it stands, and something I could keep him on indefinately. If anyone has any thoughts that could help me, responses are appreciate!
