Interestingly, this wasn't the snake's first appearance in the coop. It was just the first time he'd been caught cozying up with one of the birds.
Turns out, the wild rat snake is well-known by Allison's parents, and has come to serve a vital role in keeping the peace around the place. He lives in a broken-down car adjacent to the coop, and emerges every now and then to help himself to one of the hens' freshly laid eggs. In exchange, the snake drives away potential predators and pests that could harm them.
For that, Allison's dad actually calls the snake his "buddy."
"It has never tried to harm any chickens or their chicks," Allison said. "We welcome it because it's free rodent control. I think as long as the snake isn't harming the chickens, it should be tolerated."
Following the hen's lead, Allison decided to let the cozied-up snake be — and after checking again a short while later, found the snake had slithered away on his own.
