This is my Icelandic Stud Agi, he is very thick, very strong and muscular, but looking in this picture it appears he may have a cresty neck, this picture was taken the other day. He does have a thick coat and I'm not sure if it's just the way he's standing and the way his mane is in this picture or not. The horse has a very thick mane and it does stand up some before it goes over. He's an easy keeper, fed two flakes of alfalfa grass mixed hay, no grain gets to fat on it, twice a day. I did just put a mare in with him, to wean her foals, she adopted an orphan filly this year and they were taking her down so he got a roommate, because he won't run the mares off their food, so there is more food than he's used to. The mare is nearly back up to her normal weight, and the babies are weaned, so I could move her out, and cut him back a bit on feed.
