Ok, so they are a bit different, they thrive on oats and molasses. Fresh fruits and fresh veggies. So, this might sound odd..my sister in law has a feed store but we don’t buy it from her. It’s moldy too often. Anyways, she just gave us a pallot of horse feed. I dont have hiporsesand it’s not great for goats but they hate it. I tried giving it to mymini pigs...they loved it! It’s made up mostly of oats and mollass. It’s not sweet feed. It’s Trotter,..horse feed. Perhaps you could try some of that down the line? I don’t know, but my pigs like it and it got what your guy is supposed to eat, but it’s made for horses...odd. Our other pot bellie pigs, they are idler, we give them chicken feed, because they had a weight problem. But, while they are little, stick to their specific needs, but maybe as they grow you can try new stuff?
