I understand and Thank you all for all the help! I have been around horses since I was a child but never this young and need an opinion on how to train him with these problems. Also how do I stop him from trying to lay down on me when I am working with his feet.
Prepare yourself this is going to be long but I want to help you address everything and help you bond with your colt while maintaining his respectfulness towards you. I put a lot of thought into this for you though original.y I didn't mean for it to get this long
. But don't try to teach him all this stuff at once take it slow. Let me know if I need to clarify anything and you can PM me anytime. A few questions: How is he laying down and how long are you holding his foot up? When you pick up his feet does he start out by leaning on you before he lays down? If he is leaning on you or you feel he is about to lay down hold on to his foot and use your body and weight to push his body over a few steps . It will make him quit wanting to do that cause he will feel unbalanced. Then maybe hold the foot up for a few seconds after that if he stands straight then praise him and put the foot down. But I'd like you not have to get to that point. When you pick his feet up maybe pick it up low maybe 2 inches off the ground if he sits still for about 5 seconds praise and rub him then put the foot down if he moves away move with him don't let go of his foot if you can help it. Maybe the next day raise it higher keep it short time wise again. Next day maybe raise it normal height but keeping the time short. If he is doing that good then you can increase the amount of time you have it up, just do it slowly and give him lots of love when he does it right.
Now for his lack of respect that needs to be nipped in the bud immediately. Get either a pretty long lead rope or a lunge line when you do this might wear gloves to protect your hands. If he rears while your leading get at an angle ( 45 degrees which is midway between the head and the shoulder pull him off balance. Practice leading in a open area sometimes when you pull they fall over but that's ok just hold on to him but let the rope slide some if needed depending on the way if he falls you may walk with the line while supporting his head it will soften his fall. Every colt I've had that has chosen to fall instead of go with the pressure never rears again but letting a colt fall is usually done in experienced hands. If he bolts when you lead him plant your feet and pull his head around and make him face you he may try to go backwards after he faces you just walk with him till he stops. Then ask him to walk forward again walk him a few feet then rub and praise. Every time he turns away from you in the slightest bit turn him and make him face you then ask him to go forward. If he balks pull at a 45 degree angle get I'm to take a few steps then praise. End your leading sessions if he follows your without problems for like a minute or so love him and end it there.
Now you need to take a lunge whip with you in the pasture for a bit if he charges at you go towards him (invade his space instead of him invading yours) and whack him if he is close to you and make him back off maybe add a voice command like get back. If he is at a distance swish the whip at him up and down add voice command. Don't worry about him hating you horses don't think in those terms. If he did that to a dominant horse in a herd he would of gotten chased, bitten, kicked at or all of the above. Eventually you can change the whip to a hand gesture with voice. You don't want to get hurt and he will hurt you. Something I teach my colts is to join up. Sometimes when I go into the pasture and they are getting too much in my space I'll push them away with my body by waving extending an arm waving my fore up and down (mimics whip or the way a horse tosses its head upward) then voice cue, basically I want them to back away a few feet. Colt should back away but turn and face you. Then I turn my body at an angle point my shoulder at his face (shoulders should be squared) and extend my arm outward and slightly lowered and I don't look at them directly. When he walks up and puts his nose to my hand I'll rub him on the front of his face turn around shoulders squared and walk. You just have one colt following you so slightly angle your shoulder towards him he should follow you. This may take some practice to get the language right so don't get discouraged. Once you get it though you will achieve a mental halter on him. This is why I can always catch my horses even when they don't want to be caught.
But learn from my experience just so you see how quick they can injure you. My new colt Jackpot used to crowd me during feeding time and one day when I wasn't paying attention to him he quickly snuck up behind be and bit me hard on the forearm which weeks later still hurts cause the bone is bruised or has a small fracture. So save yourself the injury I didn't make time to teach him to respect my space so it's my own fault.So the lunge whip accompanied me after that till he learned to stay away now he waits with jet to get his food. You must make him obey your space all the time.
Almost everyday I halter my babies somedays I spend just brushing them for about 10 minutes then let them go. But I also mix it up with short 20-30 minute training sessions a couple times a week. I'll take them out brush them, then maybe have them practicing backing up, yielding hind quarters to my touch, pick up their feet, or spend a day desensitizing to whip, sacks, saddle pads, random stuff, etc. Teaching these things will help you to gain his respect as well.
What you need to remember is spend several days working on one thing at a time but don't work him everyday some days just take him out and love him for a bit. They didn't learn these things over night colt training should be slow and patient.
