Korie Robertson spoke about Phil Robertson’s well-being days before the “Duck Dynasty” patriarch died at age 79.

Last week, she told The Post that Phil’s health was “declining really rapidly.”

Phil battled multiple health conditions, including Alzheimer’s disease.

Korie, 51, who is married to Phil’s son, Willie, 53, said that watching Phil while he was dying was “so hard to watch.”

She added, “But he’s so loved, and all the family is just coming around him and taking really good care of him.”

Korie and Willie confirmed Phil’s death on Instagram Sunday night.

“We celebrate today that our father, husband, and grandfather, Phil Robertson, is now with the Lord,” the Robertson family wrote in the post.

The family added: “We know so many of you love him and have been impacted by his life. We’re having a private service for now, but we’ll share details soon about a public celebration of his life.”

The hit reality series “Duck Dynasty,” which originally ran for 11 seasons from 2012 to 2017, is back for a revival. Premiering June 1 (9 p.m on A&E) and already renewed for a Season 2, “Duck Dynasty: The Revival” revisits the Robertson family. 

As they say on the show, the Robertson family prioritizes “faith, family, and ducks.” 

The revival series now centers around Korie, Willie, and their six adult children and eight grandchildren. 

The original “Duck Dynasty” followed the Robertson family, who have the hunting and outdoor recreation business Duck Commander in West Monroe, Louisiana. 

The Season 4 premiere scored over 11 million viewers in 2013.

Phil was part of the original show – and started the family business with a patented duck call –  but in recent years, he was diagnosed with Alzheimer’s. 

“He is not able to be on the show at this time,” Korie told The Post.

She added that she went to visit Phil with her daughter, Sadie, 27, shortly before his death. 

“He’s not saying very much anymore. He doesn’t speak a lot,” she explained. 

But, she recalled that during their visit, Phil “looked up and said something like, ‘full steam ahead.’ It was so sweet.”

“He didn’t say anything else that made sense, but he just said that to [Sadie], and it was just really special.”

The family was “cherishing” those moments with him, she explained. 

Phil was married to Kay Robertson, 77. They had four adult children, including Willie, 53, Jase, 55, Jep, 46, and Alan. 

Phil also revealed that he had a secret daughter, Phyliss, 50, from an affair in the ‘70s. 

Korie said that her mother-in-law, Kay, is also not doing well. 

“She’s actually in quite a few of the early episodes of this season,” Korie explained, referring to “Duck Dynasty: The Revival.”

“As the season went on, she had some health issues, too. And she’s not been able to be on anymore,” she went on. ‘So we’re just thankful that Kay got to be on some of the earlier episodes, and we’re going to really cherish those.”
