I have been in the company of very good fanciers and national winners Colin ,all have their fads regarding vents and single tail I personally have never judged a bird on its vent ,but the single tail to me is all about balance in the hand listening to the experts ,my good cock Saddleback has not the best tail but shoulders and a back like a staffie many roads lead to Rome I am more interested in the opposite end from the tail ( what's between the lugs) Atb mick
