I have witnessed numerous percy attacks on my birds when training,it is so sickening.This year i decided that experiencd birds would have no training.I have only dropped 8 birds in 4 races,and with the weather what its been so far,i think thats not bad.I have a 3 yo cock thats returned from leicester 2 years on the trot with percy damage,he is now one of my last birds to return on raceday.
