Thanks. Thought it might be individual pigeon as opposed to individual loft. In light of this, it seems rather strange. Especially in the Gold Cup which is the Blue Ribbon race.
Perhaps the 5th pigeon had multiple performances and the first pigeon only had the one. Look at the year Walter Boswell's hen went back and placed high up multiple times. What a feat she performed. Don't know the facts or fanciers for this one though.
