Duck Dynasty’s Alan Robertson, who only joined the show last year, boasted a scruffy beard and joked that he had had to take a measure to prove he was a Robertson.

Alan Robertson also took credit for a spike in Duck Dynasty traffic when he led his parents’ vow renewal ceremony at the start of Season 4.

His wife Lisa said that the couple’s decision to leave pastoral ministry and join their extended family had been a tiring but rewarding decision.

Alan Robertson’s new look also has him eating his words, considering he was previously committed to a clean-shaven alternative.

“We all used to cut them off. But now, since they are such big stars and their beards are in their contracts, they have to keep them a certain length,” he said of Willie, Phil, Si and the other Duck Dynasty men.

“Their beards are about to get their own agent.”
