I created a buddy sour horse. Yes, It's my fault. I adopted a 2-year mustang straight from the corrals. He came in very gentle and his only vice was he cried out to horses he could not see but could smell and hear. At times he looked like he could jump the round pen so we would take a horse and put the horse in the next pen to calm him. This worked great. Next, we moved him to the paddocks as he graduated, and to keep him from anxiety we put a horse in the next paddock. 24/7. Next, we used the other horse to get him used to being in a stall and generally walking around the barn getting to know things. Then we stalled them next to each other and paddocked them together. It was truly great to see the bond until we started the groundwork and this is where I realize I did this. My mustang no longer focuses on me. His focus is, where is my buddy? if he's not near my mustang will cry out, and he will start to throw a temper tantrum, trotting around me, pawing, and neighing. It has gotten out of control, but is not at the dangerous level yet, but could be if I don't get control. I purposely, took him away from the other horse to work with him 1-1. I moved his feet every time he cried out. Boy, we did this for about 30 minutes. I trotted him on lead, we played in the puddles. and he just isn't there.
We have started to introduce other horses in the paddocks, and they still keep together.
Should I move the buddy to another stall and replace him with another horse in short monitored time-outs?
I will still plan 1-1 time and take buddy away, but any advice on this matter would be greatly appreciated.
