We are now only counting in the score a birds longest beard. Years before it was all beards. I personally do not like the change, but very much understand it. We just need to remember that the only beard that will count is the longest.
Copied from rules:
only the longest beard of a multi bearded gobbler will be scored for the Team contest this is a subject of controversy, there may be a separate Individual non typical (not team ) contest gobblers may be scored in both but in the team contest only the longest beard or spur on each leg
Also highlighted in the thread of the 2018 rules.
