How some fanciers avoid it really baffles me? pigeons don't need to be in the basket or in contact with other pigeons outside the loft to get it. I get it every year in different bouts usually just before training starts and again when the racing starts, yb racing for me over these past few years has been a no no and it disnae matter how much you clean or disinfect the place they still get it especially if your ybs are on natural.
