YELLOWSTONE NATIONAL PARK (AP) — Cooking chickens in a Yellowstone hot spring landed three people in hot water.

A park ranger heard that a group with cooking pots were hiking toward the park’s Shoshone Geyser Basin. The ranger found two whole chickens in a burlap sack in a hot spring. A cooking pot was nearby, Yellowstone spokeswoman Linda Veress said.

“Make dinner,” said defendant Eric Roberts of Idaho Falls when asked earlier this month what the group was up to in the Yellowstone backcountry.

As for whose idea it was: “It was kind of a joint thing,” Roberts explained.

Eric Roberts and Dallas Roberts of West Valley City, Utah, were ordered to serve two days in jail and pay $540 in fines and fees for the Aug. 7 incident, according to court documents.

Eric Romriell of Idaho Falls paid $1,250 in fines and fees. All three are banned from Yellowstone while serving two years of unsupervised probation.

Getting too close to and messing around with Yellowstone’s hot springs are no-nos and can be dangerous but violations aren’t unusual.

A Dutch man was ordered to pay $3,000 for allegedly crashing a drone into the park’s famous Grand Prismatic Spring in 2014.
