How Old Is The Oldest Chicken

My grandma had a hen named Gertrude who was, by all accounts, ancient. She was a scrawny thing with bald patches and a glare that could curdle milk, and she ruled the roost with an iron claw. We kids were convinced she was a hundred years old, mostly because she looked like she’d been hatched during the Great Depression and had been angry about it ever since.

So, when I finally got curious enough to ask, “How old is the oldest chicken, really?” I was a little disappointed. Grandma just shrugged and said, “Gertrude’s about eight, dear. She’s just mean.” Eight? That felt like a massive betrayal—like finding out your favorite grandpa is actually a few years younger than your dad.

But that question stuck with me, and it turns out the answer is a lot weirder and more wonderful than I expected. You see, the average backyard hen will give you about five to ten good years, but that’s just the tip of the egg basket. The real record-holders are in a league of their own.

The World Record Holder is an Absolute Legend

Forget the grumpy hens; the official title of oldest chicken ever goes to a hen named Muffy, who lived to the ripe old age of 22 years and 6 months. I know, right? That’s practically a college graduate in chicken years. She was a Red Quill Muffed Game Hen, which sounds like a fancy cocktail, but she was just a tough old bird from Berkeley, California. Can you imagine waking up as a chicken, day after day, for over two decades? That’s like 22 Groundhog Days, but with more pecking.

Muffy’s owners, not surprisingly, treated her like a queen. She flew the coop (literally, she flew over a six-foot fence to escape a dog) and earned her celebrity status by just… not dying. She was hatched in 1989 and passed away in 2012, which means she saw the fall of the Berlin Wall, the rise of the internet, and the invention of the selfie. And she didn’t care about any of it. She just wanted mealworms.

What’s even crazier is that Muffy isn’t just a fluke. The Guinness Book of World Records officially recognized her, which means she beat out every other ambitious, defiant hen in the world. That’s a lot of competitive clucking we’ll never know about.

The “Extreme” Chickens You Never Hear About

So, Muffy is the gold standard, but here’s where it gets funky. There’s a big difference between a pampered pet and a farm bird. A lot of “oldest chicken” stories floating around are about roosters, too, but hens usually take the crown because they don’t have to fight as much. But let’s talk about a hen named Matilda from Alabama, who was rumored to be 16 years old before she passed. She wasn’t a record holder, but she was famous for her longevity, which is honestly just a fancy way of saying she was too stubborn to kick the bucket.

And here’s a wild side note I need you to hear: breed matters immensely. Those big, juicy commercial chickens you see at the grocery store? They’re bred to grow so fast they often struggle to live past a year, their hearts just give out. But a bantam or a game hen like Muffy? They’re basically the tortoises of the poultry world—slow, steady, and surprisingly resilient. So, if you want a chicken that’ll outlive your kids’ goldfish, avoid the “broiler” breeds.

Okay, let’s take a quick breath. You’re probably thinking, “That’s cool, but how do they even know?” Great question, my friend. Chicken keeping is serious business, and record-keepers demand proof. For Muffy, they had vet records and eyewitness testimonies, which is more paperwork than some people have for their own birthdays. But honestly, I love the idea of a vet examining a 20-year-old hen and just saying, “Well, she’s in perfect health, if you ignore the osteoporosis and the fact that she’s a living fossil.”

Now, here’s the irony I stumbled into. My grandma’s Gertrude, who I thought was immortal, was actually a youngster. She died at the ripe old age of nine, which is already impressive, but in the shadow of Muffy, she’s a mere teenager. It makes you wonder about the chickens we dismiss as “old” in our own lives. The next time you see a scrawny hen with a bad attitude, remember: she might not be a world record holder, but she’s probably seen some things. She’s lived through a few of your life crises, after all.

So, how old is the oldest chicken? Officially, 22 and a half. But unofficially, I bet there’s a chicken out there right now, hiding in someone’s barn, that’s pushing 30 and just too ornery to tell anyone. And honestly? I hope she’s eating a slice of birthday cake. She’s earned it.
