The ones ive binned have never proven me wrong Seriously, if a bird has a dodgy makeup then its no use to anybody.You can kid yourself all you want, most birds are crap and a very small percentage ever make the grade.Im not talking about sprint/middle distance birds, im talking about the gold dust DISTANCE birds.ps. I bred a special cock last year for the stock loft, he is off International winners and the very best of Scottish distance pigeons.He has had a blood quill last year and this and now hes on the way out without breeding from him.Constitution is paramount in my loft.
