The phrase "pecking order" began with actual pecks

Every office hierarchy you've ever complained about was named after a flock of hens.

In the early twentieth century, a Norwegian boy called Thorleif Schjelderup-Ebbe spent his summers watching his family's chickens. Not casually — he kept notebooks, named the birds, recorded who pecked whom. What he found was that the flock wasn't a muddle at all. It was a ladder. Hen A could peck hen B without consequence; hen B pecked hen C, and so on down. He published the work as a young scientist in the 1920s, and the term he used for it, in German, travelled into English as "pecking order".

It went on to shape decades of research into animal social behaviour — all of it starting in a backyard with a child and some hens.

Why it still matters if you keep a few birds: the ladder is real, and it is physical. New hens are not "being bullied" by accident, they are being placed. Introductions go far better with space, visual barriers, and more feeders and drinkers than you think you need, so a lower-ranked bird can eat without crossing a higher-ranked one.

The order sorts itself out. Starvation and injury do not.

If a hen is being pinned, bleeding, or kept off food for days, separate her and speak to a vet used to poultry. 🐔
