Ive tried all the different training Frank, ybs with obs in May,tried it,leaving it till one week before yb racing, tried it. Single up, tried it. The best training I think you can do is this, 7mls, 12mls, 25mls x 4, back to 12 mls 3 times a week.CONFIDENCE, CONFIDENCE, CONFIDENCE All the above training works but the last one won me best performance ybs in Midland fed. ( thats hard to achieve where I am located ) May I also say, in the last 10 years of the Kirkintilloch club I was maybe once out the top 3 in yb racing. None of the above without HEALTH . CAN I JUST ADD, MY BIRDS HAVENT HAD A TRAINING TOSS FOR TWO WEEKS. Another key ingredient- Rest
