As a reply to all the questions:
By what I mean by 2 flakes, grass, and 1 pound, I mean morning, afternoon, and night.
One flake of coastal hay, which is what I'm using, weighs 4 pounds. (It's compacted)
Sorry, but I've got no before pictures.
He looked somewhat like this when I got him: http://www.google.com/imgres?start=1...:22,s:180,i:70
He's regularly dewormed. He's being gelded pretty soon, but I have a few questions about that. Will gelding him make him fatter? Since he's so frail, will he be okay after gelding? Should I feed him either before or after gelding him?
That saddle on him was just to see if he could be ridden. He's a very happy boy and likes being on long walks around the pasture until he gets fat enough.
