First thing first is to keep him away from your yearling fillies, and seperate from your mares. He should be kept in a well fenced area where he does not have direct contact with them and is unable to hurt himself trying to get to them.
If you are going to have him cover in hand, you will need to put hessian sacks or similar on the mares he is covering, take off hind shoes, put thick cotton wool or similar padding over her hind feet and enclose in a thick soft sack (i useally secure with bandage tape) or a pair of covering boots, this will protect your stallion from being kicked.
Have him on a reasonably long lead rope, tease the mare to ensure that she will accept him, keep him one side of a solid fence, and her the other side so you can see her behaviour. You will be able to see what her reaction is,and whether or not she is ready to accept him. They usually flash their vulva, and it will be folloed by gushing yellow liquid, this is usually a sign she will accept and is ready for covering.
He will respond accordingly, do ensure you are able to handle him as he will get over excited.
Once you are sure she is ready, bring him to your mare, keeping a secure hold of him, do not get in the way! He knows what to do, and he will mount his mare and get his job done, its part of nature, he knows what hes doing, even if hes never covered before.
My quarter stallion, first covering, i allowed him to run with the mare, once he was done, he began to graze and i got him out of there and into his stall for cleaning. It can be done that way first time so as he didnt feel uncomfortable or pressured. And after that he was fine to cover in hand as he had done it once and got his barings and knew what he was doing. I did the same with my Anglo Arabs, Arabs and welshies.
Before you breed, ensure all your vaccinations are in date.
There are several innoculations to be given to your mare. Vaccinations should be current, as any infectious disease may cause your mare to abort. A Four-way vaccine for Eastern and Western encephalomyelitis, tetanus and influenze should be administered at the early stages of the pregnancy. She will require a booster one month before her due date, this will ensure that the mares colostrum has the correct levels of immunisation from the first suckling, this is essential; when the foal takes her first milk, they are temporarily immunised against disease and infection. The mare will also require a vaccine for equine rhinopneumonitis (virus abortion) at 5, 7 and 9 months gestation. There will be other vaccines neccesary for your area, as each area is different, so you need to consult your veterinarian.
Just let him do his job and you should be fine.
