Ave used it for the last four years, But this year will be the last. The younguns are magic, excellent feathering and keen tae exercise. Have won three out o six this year and won every year with the darkies, absolutely terrific. Yearlings are poor. The same doos that won for me as younguns go down quite quick. I started this year wae 17 yearlings in my old bird team 10 of which wer darkies NONE left. Ironically the ones that fell tae bits and didny make the YB nat or fed open were the doos that performed!"!!!. Its a strange old game
