As you know I raced natural jim for more years than I care to remember ,but when the falcon problem became worse in the 90's and into millennium I had no choice but reluctantly changed to first roundabout then widowhood now celibate They get two tosses prior to racing then no more They are super fit and up with the leaders ,they are a joy to watch on a night after work racing the sky's and flying solo ,With no Stress for Pigeon or fancier I do feel that hens going to the channel need an edge so I paired what I considered my best 8 two year olds to old cocks and let them rear a youngster They now perch with the celibate yearlings and keep fit that way until being repaired when required I wish you good luck and am sure you will adjust as required Atb Mick
