Pigeons born in early May can take part in the 500 km race in autumn. Because they are young and explosive, they often become the king of speed races, but the weather that is difficult to fly will suffer a lot because they are too immature.
Under normal circumstances, early-born pigeons born from the beginning of October to the beginning of February in 65438 10 are slow to leave the flock, so they can let nature take its course in autumn, and even if they don't deal with big strips, they can successfully complete the race.
