Agree 100%,if they are unable to get home say its last years ybs and have had no training or racing and been on open hole all the time if they don't know where their loft is after that they are duffers,first and foremost they are homing pigeons,i have not trained or raced ybs for a long time now and they hold their own against birds that were trained and raced hard as ybs,again its only my opinion,the main reason I stopped racing ybs was to find out if it was the best way to stop getting yb sickness plus the rest of the stuff doing the rounds,it works stress free for my ybs and me I love it and so does the ybs.OMO.
