I've looked into this question. Depends on the size difference and the willingness of the mare, but if she is winking, etc., many times the mare will lie down or crouch to allow the smaller stallion to mate. As for the foal size and reaching to nurse, there was a study done in England in which shetland fertilized eggs were placed into draft horse mares, and the other way around. Unique to horses, the mare's uterus has hormones which control the size AT BIRTH of the foal. So a shetland mare's foaling of the draft horse baby (which had been implanted) was not impossible because her uterus kept the baby small (and he later made up the difference by growth spurts to catch up to his true size). Similarly, the draft mare's foal was larger than usual for a shetland foal. So, if you have a 14-15 hand mare, it is theoretically possible that the foal will be able to reach. Nature is against it working, both at conception and after birth but it has been known to happen.

By a mare and a stallion meeting. You get the gist.
There is no lead stallion. There is Alpha Mare. SHE leads the pack. But a stallion in the pack would breed with most every mare.
You are really not supposed to, due to the fact that both the mare and stallion run the risk of getting injured.
Having a mare breed with a stallion.
A stallion only needs a mare.
No. A stallion is a male horse that can still breed. A mare is a female horse.

A stallion donkey is called a Jack. A jack will try to breed a mare, but the mare may not let him cover her, even if she is in season (ovulating).
You could have several possibilities. A small, tall or in between sized horse. It mainly has to do with genetic coding in the womb and once the foal is born the nutrition and care it receives.
A mare and stallion breed and make baby called a foal.
Every breed comes in mare and stallion, so it just depends on which one you have. Or just /check/. :)
Wild horses mate in the same way as domestic horses. A mare that is in heat will urinate and present herself to the stallion. The stallion will sniff the urine and then the mare, typically displaying the flehmen response. So long as the mare is receptive the stallion will then mount her and breed with her.
