The second longbeard I shot in WV this year had a 9 1/2" beard, 3/4" spurs and he weighed 14 lbs. That is the second bird I have shot in that area that had a very light weight...the other was about 7 or 8 years ago and weighed 15 lbs, had a 10" beard and 1 1/4" spurs. I could not see anything visably wrong with either turkey and both gobbled as if they were healthy birds.
