No fps- approved stallion is allowed to carry the red gene, so its pretty rare. However, since studbook registration for mares does not require testing, it still pops up occasionally. You can't breed them (not if you want registerable offspring, anyway) but I do think they are pretty :)
wow!! Those horses were beautiful!! I loved the red coat and the grey/white was stunning. I think the reds must be a cross of some sort becuase everywhere I've read says that I fresian must be pure black or very dark bay to be considered a purebred. But still I'm amazed!!!
Love your horse, you may leave the stable and never here their playful whinny again.... Take it from a person whos experienced this.
