"Duck Dynasty" star Phil Robertson's health isn’t good night now, according to his son and former co-star. Jase Robertson opened up about his father's health on a Wednesday episode of the family's podcast "Unashamed With the Robertson Family." "The number one question I get everywhere I go: 'How’s your dad doing?'" he said during the episode. "Now, I’m just giving the blunt truth: I say, 'Not good.'" The family patriarch was diagnosed with Alzheimer's disease. He added that the Robertson family is doing the best they can. Despite their dad's health concerns, Robertson revealed that their mom Kay Robertson is recovering after a fall.
