Onyx is a gorgeous blue roan AQHA mare with serious foundation breeding and a ton of athletic potential.

Sired by Leo Hancock Hazz (Leo Hancock Hayes x Blue Valentine lines) and out of Mucha Blue Valentine, she’s stacked with Hancock / Blue Valentine / Rowdy Blue Man blood—known for bone, feet, brains, and ranch using horses. If you like old-school, cowboy-bred Quarter Horses, she checks that box.

Highlights
• 5 years old, blue roan, registered AQHA
• Barefoot, trimmed every 8 weeks
• No buck, no kick
• Bottom of the herd – not dominant, easy to keep in a group
• Ridden frequently by two trainers on my property
• Still green butcoming along nicely – just needs someone to finish her out
• Very athletic – has cleared a 5 ft fence twice; could absolutely be a ranch / rope / cow horse or a nice jumper / all-around using horse
• Needs something other than a plain snaffle – regular snaffle pinches her tongue, so she goes better in a different mouthpiece style

Job Potential

This mare needs a job and will shine with consistent work. Great prospect to:
• Check cattle or ranch work
• Pony horses / track work
• Take English and point at jumps
• Versatile all-around trail and using horse with the right miles

Full Disclosure – Cribbing

Onyx is a cribber. She wears a cribbing collar, and we have hot wire on all fencing. With the collar + electric wire, she does not crib in our setup. Any buyer should be comfortable managing a cribber with appropriate fencing and a collar.

Only reason for sale: she’s too nice to stand around. She’s a young, athletic, foundation-bred blue roan who’s ready for someone with the time, energy, and a plan to turn her into the kind of horse her pedigree promises.
