Congrats on your foal-to-be. What are your plans for it? What do you do with your Minis? Your mare seems very young to have already had one foal. Are you sure about that? Seems you have all your ducks in a row and are getting prepared. I imagine you know that Minis are notorious for having pregnancy and foaling difficulties. According to what is known about the horses in the pedigree, have both been tested for Frame?
Who is the stallion? Unfortunately, there are many Minis by that name. Same withe 'Honey Bee'. Minis seem to share many of the same names. I suspect you mean that your mare is a ggrandaughter of Boones Little Buckeroo? We have a great grandson of his also. Ours is gelded. Nice pedigree but not top breeding quality. Buckeroo has literally thousands of great grandchildren about now.
Insist on seeing pictures here!!!
