Anyway, he was all fuzzed up in his winter coat when I went to look at him. He was on a semi-dry lot with, which looked like, a lot of hay, and 2 other large ponies/horses. He never looked like he had anything wrong. Brought him home a couple weeks ago and started shedding him out. I do have a lot more grass than he previously had. Introduced him slowly to the grass, feeding same grain amount and same kind, and a little less hay since there is more grass. After about 3 weeks of having him, I recently noticed his neck is super thick and hard. "Cresty" in other words.
Should I be limiting his grass intake more? What can I do to prevent and help fix his Cresty neck?
