ST. PAUL, Minn. - The clucking, the bright yellow "Chicken Crossing" sign.

Both signs you're in the Jokelas' backyard in St. Paul.

"We like the chickens, then we have our own organic eggs," said Melissa Jokela.

And there's sweet little Creamy.

"I love Creamy. My nieces actually named her," said Jokela.

Cream Puff, or Creamy for short. She's one of five chickens living in the Jokelas' backyard hen house.

"She would roost right up here. Right under, she liked the wind chimes," said Jokela.

But with wind chills below zero this winter, Creamy spent one night out when she shouldn't have. She got frostbite and lost her right foot.

"She'd hop on one foot, so it was as fast as she could go," said Jokela.

Since she couldn't run, Creamy was vulnerable outside, so she had to spend most of her time indoors. Melissa and her husband, Alex, wanted to get her some help, so they asked around at the University of Minnesota and heard about "Makerspace," a student-driven innovation lab at the U's Bio-Medical Library specializing in helping people learn how to use and apply 3D printing.

"The first animal we have helped, yes," said Jonathan Koffel, an emerging technology strategist with Makerspace. "3D printing is like a hammer. It's just a tool. It can be used for so many different things, for printing out fidget spinners for kids to making prostheses for hens."

Melissa Jokela, who works at the U, sent customizable dimensions and Koffel started printing.

"It's probably about 25 cents worth of plastic to print it out, maybe a few cents worth of electricity. So, we're able to do multiple different models, we can even do it in different colors so that Creamy can match her prothesis to how she feels that day," said Koffel.

Creamy picked a pink foot, which got her back outside for good.

"She's able to run, she's able to walk, she keeps it on," said Jokela.
