That bird's sire was Mister Cooper. He got that name by the way he out foxed a young Cooper who tried to eat him, when he was only about seven weeks old. Mr. Cooper was a 1st generation Smith. He was a member of my 1st YB team in 2003, and managed to score high enough to make the United Pigeon Combine's Bird of the Year List. I no longer have Mr. Cooper, but there are 42 descendents recorded in his data base. He was sold and replaced by other 1/2 brother's, I let a couple brother's go to you, their number's are 919 and 903. Grand children of Ludo's Late Rode 430 and perhaps more critical, full son's of none other then the Duke of Earl of which 123 descendents are within the SFL data base. Among them, Ace's, 1st Place Flamingo, cash winners from Winners Cup and other Flamingo events, and perhaps 50% of my breeding colony.
Your experience, simply confirms mine, thank you for sharing. A few more performances like that, and she may be breeding material. If you decide to breed towards the Claessens standard, I will share with you, what may be the definition of an ideal or "Perfect" Claessen bird. If you should ever happen across a bird which looks like this, ignore any pedigree or "name" and simply buy the bird.
