Yea he full grown - sometimes they can get beard Rot and just hav 2-7 inch beard and I am guessing they can also hav no beard
I called a few spurless birds - my buddy killed a monster w like 1 1/2 inch spurs that had like 3 inch beard - beard rot -

one of the toughest birds I ever hunted had either no beard or a Jake beard (I did not see a beard) called him in different times - shot his subordinates each time - one had 1 1/4 inch spur and the other bird had 1 5/16 - never killed that beardless or Jake beard bird

I always shoot a bird w full fan
