I don't know about her. When I was showing my 1/2 arab gelding in the mid 1980's he was a hot stallion in VA. However, many of his get were a little bit crazy when it was time to break them. Also, they were spectacular weanlings, beautiful yearlings, pretty 2 year olds, and tended to get quite plain as they got older. That is not saying your mare is, but I did see a lot of that.
I have a 10 year old mare by this stallion. We picked her up for little or nothing. What could be wrong with this mare, I can't find a thing. I guess I should not look a gift horse in the mouth.
