Is Big Bird a Really Big Chicken?

It's the question that has haunted RBC (Really Big Chicken) headquarters since the day we opened our doors: Is Big Bird a really big chicken?

At 8 feet 2 inches tall and covered head to toe in yellow feathers, Sesame Street's most famous resident is, by any reasonable standard, both big and bird. But is he a chicken? And if so, does he qualify for RBC certification?

After weeks of internal debate that nearly tore the organization apart, the RBC Research Division has completed its official investigation. What follows is the most rigorous analysis of Big Bird's species classification ever conducted by a really big chicken authority.

The Case For: Big Bird Is a Really Big Chicken

Let's start with the evidence in favor.

1. He is big. At 8'2" and an estimated 300+ pounds, Big Bird would obliterate every record in the RBC breed rankings. For context, the tallest chicken breed — the Malay — tops out at about 36 inches. Big Bird is nearly three times that. If Big Bird is a chicken, he is not just a really big chicken. He is the biggest chicken that has ever lived. He would score a perfect 47 on our evaluation system. He would break the system.

2. He is a bird. It's right there in the name. Big. Bird. The man isn't hiding anything. He's not "Big Mammal" or "Big Ambiguous Vertebrate." He has feathers. He has a beak. He has two legs. By the transitive property of poultry, he could be a chicken.

3. He is yellow. Many chicken breeds come in yellow, particularly as chicks. Big Bird's uniform yellow coloring is consistent with a chicken that simply never outgrew its baby plumage — which, given his childlike personality, tracks.

4. He lives in an urban environment. Backyard chickens are increasingly common in cities. Big Bird lives on Sesame Street, which appears to be in New York City. This is exactly the kind of urban chicken situation that RBC documents regularly — just at a different scale.

5. He cannot fly. Chickens are famously bad at flying. Big Bird has never been observed in sustained flight. Coincidence? RBC thinks not.

The Case Against: Big Bird Is Not a Chicken

In the interest of journalistic integrity — which RBC takes as seriously as chicken bigness — we must present the counterarguments.

1. Sesame Street's official position. According to Sesame Workshop, Big Bird is a "golden condor" or simply a "large yellow bird." At no point have the show's producers identified him as a chicken. RBC acknowledges this but notes that self-identification is a complex issue, and Big Bird has never explicitly denied being a chicken either.

2. His height is physiologically impossible for a chicken. Even the most generous interpretation of chicken genetics cannot account for a bird standing 8 feet 2 inches tall. The largest chicken ever reliably recorded was approximately 30 inches. Big Bird exceeds this by a factor of roughly 3.3x. Our scientists describe this as "outside the normal distribution" and "frankly, ridiculous."

3. He can read. Chickens, even really big ones, cannot read. Big Bird is literate. He has been observed reading books, street signs, and letters from his pen pal. This is not typical chicken behavior. Colonel Massive, the largest chicken in the RBC database at 19.8 lbs, has never read anything.

4. He has a best friend who is a woolly mammoth. Mr. Snuffleupagus is an 8-foot-tall woolly mammoth-like creature who only Big Bird could see for many years. While RBC does not judge chickens by the company they keep, the mammoth thing is unusual.

5. He sleeps in a nest on Sesame Street. Okay, this one actually supports the chicken theory. Moving on.

The 47-Point Analysis

Setting aside the species question for a moment, let's evaluate Big Bird purely on the merits of his bigness using the official RBC 47-Point Evaluation System.

A perfect score. The first in RBC history. If Big Bird is a chicken — and we stress the if — he is not merely a really big chicken. He is the really biggest chicken. The Incomprehensibly Big rating was designed for exactly this scenario.

Expert Opinions

"Big Bird exhibits several chicken-adjacent behaviors including ground-dwelling, seed-eating, and an inability to fly. However, his ability to hold a conversation and ride a unicycle places him outside the standard poultry classification framework."

— RBC Chief Science Officer

"I've been evaluating big chickens for six months now, and Big Bird is the most challenging case I've ever encountered. He's clearly big. He's clearly a bird. But 'chicken' requires a specificity that I'm not sure the available evidence supports. That said, I want it to be true. I want it to be true so badly."

The Official RBC Verdict

After extensive deliberation, the RBC Board of Directors has reached the following conclusions:

1. Big Bird is, without question, really big.

2. Big Bird is, without question, a bird.

3. Whether Big Bird is a chicken remains officially unresolved.

4. If future evidence emerges confirming Big Bird's chicken status, he will be immediately inducted into the RBC Hall of Fame with the highest rating ever awarded.

5. RBC has formally written to Sesame Workshop requesting clarification. We have not yet received a response. We will wait as long as it takes.

In the meantime, Big Bird has been granted the title of Honorary Really Big Chicken — a new designation created specifically for this situation. It carries all the prestige of full RBC certification, with the caveat that the "Chicken" part is aspirational.

What This Means for RBC

The Big Bird investigation has raised important questions about the boundaries of RBC's mission. What does RBC stand for? Really Big Chicken. But what counts as a chicken? Where does "chicken" end and "large yellow bird of indeterminate species" begin? These are the questions that keep us up at night.

For now, we remain committed to our core mission: documenting, celebrating, and ranking really big chickens. And if Big Bird ever comes forward and confirms what we all secretly hope — that he is, in fact, the world's biggest chicken — RBC will be ready.

We've always been ready.
