its a long curve to get too the top or to compete at the top what u have to remember u are racing against people who are in this all there lives some are itts no easy i bet one of your big downfalls is feeding new starters tend to be to heavy with the feed or feeding the wrong type corn u would seem to have a clean bill of health so your loft doesn't seem to be the problem remember Rome wasn't build in a day
and belive me giving baytil every week before a race wont work either this person is of very low intelligence when it comes to pigeons or wants to put u wrong u can work that out for yourself maybe what distance u are flying what the loft conditions are like maybe in even a pic of the inside of the loft i bet we can help here but remember it takes more than a week if only ;D ;D ;D
