I was recently given a 19 year old TB gelding. I was already familiar with Calvin because he came from a stable I had worked at for about four years. I never saw anyone work with Calvin execpt for myself and that was only to lead him to his stall and pasture. I took care of 25 horses so had very little time for Calvin. He seemed to have a sweet dispositon but would somtimes spook and slightly rear when being led. My old boss/trainer said he wasn't difficult to ride but that he carried his head way to high (almost bashing you in the face while trotting).
Now, two years later Calvin was given to me because it cost to much to feed him (due to sever drought). Hay shot up to $9.50 a bale. I have had him for two weeks and at first things were fine. I knew he was a bully so we have only done ground work. He won't tie, and he leads horribly (ripping sockets out to eat grass...ect.). He started getting better until the other day I went to loung him (third time) and he went crazy on me! Buck and rearing and would not lounge at a walk for nothing. He will now spook by jumping straight into the air off all four feet. Sometimes away from you most of the time towards you. Confronting spooky things is likely to get me killed (not joking). We can't even pass spooky things at a long distance (200 ft).
His feed is 2 quarts of sweet feed in morning and evening with all the hay he wants.
What should I do?
