Whenever any of mine had hit the wires they rarely needed stitching, as they repair themselves very quickly, they would just need a good clean! As far as racing, I wouldnt bother racing them again, if you have a heart and its a bird you want to keep. I had a really good blue cock that had won twice and he returned back from a 550mile channel race on the thrid day all smashed up, it was a miracle he made it home, he was left in the aviary to heal and then wintered. He flew round the loft 100% as he used to, and got in to race condition before the next season. The first race he went to he never returned (60miles), after all the races he had been to and cards he had won I was gutted and vowed never to send one like that again!
