I've missed this place a lot, and I know I owe an explanation of my abscence but for now I need your opinion on what this could be!
I moved my horse to my house (he was boarded for about 4 months under my ownership previous to this) about 4 months ago and he has been a different horse ever since then. He is difficult to catch (which isn't a big deal at the moment as he is on stall rest for a few weeks), he moves away from me when I go to pat him.. he sometimes even cowers down if I move too quickly. He is spooky and jumpy at everything. It is a small battle every morning to put his fly mask on until he realized that he has worn a fly mask a million times before. He used to be really bonded to me but now he acts like he did when I first got him... Distant and almost disrespectful.
The factors that have changed are:
-He hasn't been ridden but twice in the months he has been here... When he was boarded I rode 3 times a week.
-Feed. He was on Patriot before and is now on Ration Balancer.
-He no longer lives with horses, though there are two mare in an adjacent lot.
The weird thing is I took him to the vet last week and he acted perfectly. He let the vet pick up his feet easily, he was quiet and not spooky at all (he was falling asleep in a busy room) and he loaded quietly there as well. He seemed really dependent on me there though... I left to go to their office and he was whinnying after me and pranced around a bit.
This is my first spring with him, but I was told he is an air fern. However, I am having to feed hay in addition to his grazing because he is skinnier than I'd like.
Is this anything to be concerned about?
