Oh, I hate separation anxiety in show cattle.
I showed a pair of square meater heifers a few years ago, they were perfectly fine and I had no inclination that there was a problem . . . till I took them out in the ring. They were in seperate, consecutive classes. Both of them were nutcases. They would not stand still, they were jumping, kicking, one put her head down and charged off into the limousin ring next to us, the other one charged off and climbed up the bleachers which were full of people (with me still in tow, in both cases) -- oh boy, they were completely nutty.
I've never been able to cure it totally. Best thing I have found is to prevent it, rather than cure it. But just try leading him away from the others, by himself, just for a short time, then increase the time he spends away from them.
Good luck with the separation anxiety, and good luck in Denver!
Oh by the way,
Any potential behavior issues to worry about if we put him by himself?
Yep, he will most likely go off his feed, lose weight, stress, may be restless, kicking or flighty when you try to handle him.
The worst case I had, the steer was lifting the gate off its hinges (heavy duty cattle panels) to break out. He broke everything in the yard, the steel drinking bowl, the steel water pipe, the feed troughs, the gates . . . the posts in my show cattle yards have never been the same since - they are concreted in, and the sucker managed to move them. Course, he was a crazy son of a ----- since the day I got him. That was why he and another steer had been left home while I took the rest to a show. Oh boy, he let me know he didnt appreciate it in the slightest. Needless to say, he came to the show. Needless to say, it was a terminal show. I was so happy to put him on the truck off to the slaughter :lol:
