Over the last week, he went from showing interest in his dam's food to straight up eating it. Today, I'd guess he ate 1/8 of her evening ration. He's also eating hay, grazing when he lays down, eating leaves off branches he can reach and will nibble at a soggy horse treat. I'm not talking general interest here, I'm talking actively seeking out solid food, chewing and swallowing. When I take his dam on walks in high grass, he eats what he can reach when we stop.
Should he eat that much this early? He's keeping his mom's bag low from constant feeding, and he's a BIG boy with teeth, but is this out of the ordinary?
If it helps, he's a Tennessee Walker colt with a 15h dam and a 16.1h massive sire. The pic below is of him at a week old. He's filled out a LOT since then, he looks like a refined QH.
