Selling a stunning, large-framed mare from the successful Holsteiner bloodline 730b!  
She has an excellent temperament and outstanding basic gaits.

Her foals have almost exclusively been sold at auctions for very high prices.  
Last year's filly achieved a top price of €17,500 at the Hörup auction.

Miss Chica is the fifth mare in a row to receive either State or Verband premium awards on her dam's side.  
She is scored 53 points.

Her dam is the full sister to the licensed stallions Zornell I and II.  
Both have proven themselves in the higher levels of competition, with Zornell II having successfully competed twice at the European Championships for Young Riders.  
Zornell I was sold at auction for €180,000.  
Her full brother, Cancoon, was victorious in show jumping over 2.05 meters, according to her pedigree.

Whatever else you would like to know,  
please feel free to call me.
