I have cut back by closing another breeding pen. Wittenbuik Princessje 40 is from my insurance pen - never bred from.  

Sire: Super YB Racer, Determination 6105, #2 Champion YB All Boston 2016 - any distance - see his extraordinary race record below.  His sire is a son of The Perfect Cock, who in turn was one of the best breeding sons of the great Shadow.  Determination 6105's dam is Super Diamond 648 one of the best breeding hens I've ever imported from Mark Evans, the Gaby Specialist - in her first year breeding alone she bred a fantastic, 5 X's 1st/= 1st.  

Dam of Wittenbuik Princessje 40 offered here is Wittenbuik Princessje 127, Super, Super  breeding hen - Toppers and Champion Birds in both YBs and OBs.  Wittenbuik Princessje 127 is an imported, direct daughter of two of Europe's Superstar Gaby breeders: Pre Olympic and Wittenbuik Princessje, Wittenbuik Princessje 127 is Super Star bred.  Pre Olympic, breeder of 6 National Champions, was called by a magazine writer, "The best Dutch racer of his decade!"  Wittenbuik Princessje was one of the best ever, inbred Wittenbuik-blooded breeders.
