The “Ducky Dynasty” has added another duckling to their flock.

Jep and Jessica Robertson introduced FOX411 to their 4-month-old son Jules Augustus, who they affectionately call “Gus.” The parents of five spoke to us about their growing family and new A&E spinoff show, “Jep and Jessica: Growing the Dynasty.”

“I actually went to the Dominican Republic on a little missionary trip and I saw those kids there, and it really changed my life," Jep told FOX411. "I came back and told Jessica. I saw things…there’s an orphanage there, and we would bring them like Hanes T-shirts, and they never had anything new and they would cry, and grasp the shirts, and I thought, ‘Man, there’s so many kids in need.”

The couple looked to their family members Willie and Korie, who have adopted before.

“We’ve leaned on them a lot, and asked them many a question,” said Jessica.

When asked about being the mother to Gus, the 35-year-old mom welled up with tears.

“It’s pretty extraordinary," she said. "Like I said even on the show, your heart expands so much, and just to know and he wasn’t here a few months ago with us, it was all God’s plan to bring him in our lives."
