I was seeing a flock of turkeys back in October while bowhunting and 2 hens in the bunch had beards like the one you speak of, Tree climber. I rarely ever see a bearded hen period, let alone two in a single flock, plus they both had fairly thick 8" or 9" beards too. I don't know how rare a sight that is in general, but in my neck of the woods, you don't see a sight like that every day, that's for sure!
