This is my yearling Quarter Horse gelding. He's going through a massive growth spurt at the moment (last Saturday, I sticked him at 12hh. Yesterday, he was 13.1hh) and eats as much as the barn owner's full grown mare. He is on the pasture and fed hay twice daily. He's in the process of developing a grass belly, as you can see, and was last wormed on July 17.
I think he's just growing too, but I'm hearing so many conflicting opinions on him that I figured I'd ask. I come from a racing background and all the horses were very lean, so I'm not exactly sure what a pleasure horse should look like at a year old.
You are seeing ribs and thinking skinny, but there is more to it. He is carrying good weight over the rest of his body, so chances are good that he is just going through a phase in his growth. As ilovemyPhillip said, just keep the feed to him, and wait it out
I don't think a horse could grow 4" in 1 week. If he grows to fast you going to have more problems with his legs and bones. Not sure of the term but it is very serious that they do not grow too quickly
Re: Supplements -- I don't have him on anything yet, but I'm doing some research to figure out what the best thing for him. He does get a mineral lick, but aside from that... I'm trying to decide what the best supplement for him would be. What would YOU recommend?
He also needs some muscling and we're working on that.
Re: His massive growth - I was shocked too! I've never known a horse to grow so quickly either. His legs are like tree stumps (the pictures don't really do them justice) and his hooves are massive.

That is a good thing to mention, churum, and something to consider, OP. That is another major contributor to chronic unsoundness in halter horses, they are over-fed with rich food to maximize their growth and muscles and they grow so large so quickly that it screws up their legs.
That being said, a bit of rib on a growing youngster is perfectly acceptable. You can tell that he is otherwise very well cared for and well fed. He'll gain it back in time. He's a good looking boy.
