Hi Neil, Mickys birds really do exercise very well at home so i am told, not just by micky, but by the fanciers who live locally. Whether they fed before or after flight i couldnt say my friend, however i imagine the use of superstar plus, would be due to the fact the expect their birds to perform from the short races to the long distance races, with no pigeon being specialised for one or the other, but then again that would be a guess again, as its not a question i asked at the time. Regards Ryan
