"Fixer Upper" stars Chip and Joanna Gaines introduced several "pig" additions to the family Tuesday — just days after announcing the birth of their fifth child, a son named Crew.

Chip posted a photo of six piglets resting alongside a larger pig, presumably their mother, on Instagram early Tuesday.

“Errbody having babies round here.. #farmLife,” Gaines, 43, quipped in the caption.

The post has received more than 515,000 likes and thousands of comments as of Tuesday afternoon.

“Awwwwwww!!!!!! Don’t drink the water around the Gaines family,” one fan joked.

Another added, “Geez, more babies. I want to live at your house.”

“Squealing for this mamma for her piglets and, of course, proud parents to Crew!!” an Instagram user wrote.

Chip tweeted about his days-old son earlier in the day.

“Newborns are AMAZING! #sleepyTho,” he wrote.

Chip welcomed his youngest child to the world on Saturday.

"And then there were 5. The Gaines crew is now 1 stronger!" Chip tweeted. "10 beautiful toes and 10 beautiful fingers all accounted for, and big momma is doing great!”

Joanna also gushed about her newborn son on social media.

“Our baby boy, Crew Gaines, is here and we couldn’t be more in love,” she captioned a Sunday Instagram post. “He made an unexpected (and speedy) entrance into the world two and a half weeks early - which is fitting given he was a sweet surprise from day one.”

The couple are also parents to daughters Emmie Kay, 8, and Ella 11, and sons Duke, 9, and Drake, 13.
