Fantastic job and good example of nutrition. I got some horses from the wild last year they were terrible when I got them skin and bone. The colt, had this big head and tiny underdeveloped body, his teeth aged him to be about 2yrs...well a few months of vitamens and a bit of feed, plus a mineral block (nothing fancy at all), he aged two years his body filled out and his teeth changed completly, he got all his four year old teeth it was amazing. Nutrition is so important.
Sorry my internet is too painfully slow to upload pics, but go to www.wildhorseproject.blogspot.com
and look at the slide show or back to the first few posts and you will see what I mean. Its amazing how much they can change.
Again well done for your boy!
