I have bought my first mini, she is a mare and is in foal to a shetland stallion. I'm curious as to why people do this cross? Is it done very often? What is the purpose of it? I'm just trying to learn all I can before my first foal is born. I did get an application to register the baby from the former owner in some sport pony registry? I would love to hear any information on this cross! Thank you!
