I am buying a 3 month old colt that I would like to remain/turn into a stallion. I would like to teach him to be well mannered and to give specific commands for breeding, so he does not associate breeding with every mare he comes into contact with. He may anyway, but if there is a way or a system that you know of, please let me know. I know of a couple stallions that are crazy and I don't want to regret leaving him au natural! I also want a recommendation on whether to keep him totally separate from all horses, or if being around his own little herd will help.
There are several things you can do with your colt to make sure he remains a well-mannered stallion. First of all, let me say that in my opinion, there is no excuse for a poorly behaved stallion, other than poor training and handling. There are many breeding stallions that are just as well behaved, if not better, than the average gelding. It is simple a matter of training and discipline.
Socializing a young colt with other horses is VERY important. He should be turned out or housed with other geldings as much as possible. You cannot allow him to hang out with fillies or mares, from the time he is a yearling on, because he can and will breed mares. But if he is stabled with other geldings from the time he is a yearling on, he will be much happier and better socialized to herd behavior. I would highly recommend this plan if it is an option.
Some older breeding stallions may not tolerate geldings well, but many will remain "gelding friendly" throughout their lives. As for breeding, first off, I would recommend NOT breeding him until he is 3 or 4. Sometimes breeders will do "test" breedings of a young stallion as a 2 or 3 year old and breed to one or two mares. Just remember that he is still a youngster and needs to focus on his performance training during this time. Once he goes to the breeding barn, his priorities will change. Breeding takes a lot out of a horse physically and it will be tough to focus on his training. It has also been researched and proven that the foals produced from very young or very old stallions (and mares) are not their best get.
When you do start breeding him, it is critical that everything associated with breeding is completely different and separate from the other parts of his life. For example, you use a totally different halter, have a separate area for breeding and teasing and have a different set of rules for handling him when he is breeding (behaviors that you would otherwise disallow, like hollering and squealing, nipping and strutting, sniffing and fondling mares are acceptable when courting a mare). When he is going out of his pen for training purposes, he should not even be allowed to turn his head to look in the direction of a mare without receiving a correction from you. Breeding stallions learn very quickly that putting on the one halter means we are going to work at the training barn now, while the other halter means, yee-haw! We're headed for the breeding shed! Many breeders use a halter bit in their breeding halter, which not only gives you a better handle on the horse, but makes it even more clear to the horse that this is the breeding halter, not the training one. As your colt matures into a stallion, he will naturally become more dominant and possibly aggressive (if this is tolerated).
It is important to maintain strict discipline and make sure that the person handling him is dominant. Behaviors such as biting are very common in breeding stallions, but this vice will only develop if his handler tolerates it. It is best to "nip in the bud" any such behaviors as a youngster. Be very firm and very disciplined with him and give him lots of training early on, so that you can fall back on this training as he matures into a stud-muffin. Lots of round-pen work and lead-line work will be beneficial in developing a relationship with your colt in which you are clearly the dominant one. Be very consistent in enforcing your behavioral rules for the colt and he will learn from an early age to follow the rules. I can tell already that your colt will turn into a very nice and well-behaved stallion. By addressing these concerns early in his life, you will give him a great start and he will turn out to be the charming young horse you want him to be.
Good luck and I hope these answers have helped.
