He IS solid!! Great work on him, he's looking fab!
What are you feeding him on? My mare has the 'weight' now, but trying to bulk her out more and she still looks very narrow :S
Am feeding what I put in my intial post to this thread :)..I did add a muscle mass builder (smartmusclemass) to help the process along a little in the first 8 weeks but have stopped that now that he is getting much more consistent exercise and turnout. He is on a pre- and probiotic, (SmartDigest Ultra) and Grand Complete which is the hoof/coat/joint combo.
