In the past (think mid nineties was last time)we have tried the racing kits of youngsters - but to no avail (none left at end of season etc, they was healthy enough but that was all.
then we tried their allfair auctions, Staf Van Reet strain - bought three 1 @ £240, 1 @ £110 and 1 x £90....never bred a performance pigeon in the 3yrs we raced their offspring (actually the £240 bird was bought as a grand daughter of daniel and after 3 months of trying to pair to our No1 stock cock, actually had to find a hen for it, cos it was a cock & this was a 3yr old pigeon)
Then as a benefit of the doubt in the 2001 we tried a couple of their pedigree pairs they sell during the winter at £75 per pair.......only to recieve them by amtrak to find a pencil cock with mild PMV (actually neck/head on one side!!)
Spoke to Micheal, and his response was "we are a breeding stud and with the number of birds we send out there is bound to be some abnormalities" - what a sack of kak.
These birds were returned and will never be used again....we gave them 3 x chances...i think that was fair....But we know other fanciers who have had them and score with offspring, just not us?
