Aye but your yearlings were raced as youngster alan true ? I think young birds at least need trained ,I've always trained mine sometimes unraced or maybe one or two races , I used to race them right out , then I brought in the black of dromore pigeons took me nearly 5 years to work out how to race them , I found then if I raced them as youngster most went down like snow off a dyke ,but give them an easy race or two let them mature then bingo ,wow best pigeons I've ever had .so I think different birds/breeds need a different approach. So good luck today Andy .me personally I think yoo/ the birds will need it .
