Big are you referring to the gaps that create a 'half a pizza' type look? That splits the fan into groups of four feathers? If you are.... that is pretty normal with B Mobile and I wouldn't sweat it. None of the turkeys I've shot over him have given a rip. Gobblers in the wild have missing and broken tail feathers on a fairly regular basis. If that isn't what you are referring too, then maybe if you could put a picture up so I could see what you are dealing with I could help out a bit more.
