I very seldom kill a racer, they have to work in this loft , so anything that lasts the pace has earned its perch for the year.Saying that, I wont push a bird that hasnt had a great moult, your wasting your time.I pay particular attention to the moult of a pigeon. I grade every one and although they all look great, very few have an exceptional moult. The ones that do, almost always win the following season.99% guaranteed
