I have 2 questions on how to handle a situation with a young, green horse.
1. I guess it could be describes as jigging in cross ties. Not to an unsafe extent, it`s more like a restlessness.
Don't tie him until AFTER you've worked with him. Give him a reason to stand still. He's got energy and you're asking him to just stand there and that's like telling a four year old kid to eat candy and take a nap. Make it easier for your horse to want to stand still and quiet.....so, if you work with him first (forgo the grooming and just work with him on some ground work)....then go to the cross ties (he's taught to tie, correct?) then the cross-ties will be the resting place and he'll be willing to stand calm.
Then it'll turn into a routine where he sees the cross ties and just relaxes. Then you can go to the cross ties first and work with him after.
2. Calling for the herd. It makes me nervous because I worry that one day this will be followed by a bolt or a buck, and I`m surprised it hasn`t.
I can tell him to quit, but how to I enforce it...
calling for the herd is his way of telling you he's got time to think of other things but you. This means, he's telling you that he really needs you to step up and put that anxious energy to better use than just calling.
Stop thinking about..."this calling can turn into a bad situation.." because your own lack of confidence is affecting him as well and can also cause the calling.
Instead...you focus on what you Do want him to do...speed up, slow down, stop, turn left or right, one rein stop, back up, etc... etc... (all with moments of a release of pressure of course).
Then when you feel that he's calm and he's not calling, let him move out on a totally loose rein.
The moment he starts to call out, put him back to work (not punishment) again....focus on making each thing you ask him to do better than the last time...so focus on...getting him to give better, etc..
Your focus + How you are cueing him = How well he responds + last his focus
It starts with you. Not him. If you are reacting to him, anxiously dreading bad things....then you're giving him a reason not to trust you. And the calling persists.
But if you ignore the calling (don't punish it) and instead focus on what you Do want him to do....then he'll come around and he'll choose to stop calling because he'll feel secure in you.
The only way to stop it is to give him a good reason to stop it....show him that you are confident and in charge and he'll gladly relax and stop calling (he won't have a reason to call for the other horses, because you'll be his herd leader).
