There is a poultry show next month that I plan on taking some of my birds to. One of my birds is a young OEGB cockerel that I'm pretty proud of. Only problem is that he is not dubbed. The show is on the 18th of December, is it too late to dub him for this show? I don't know how to do it, but a friend does. The cockerel is about 8 months old.
