How many chickens have been eaten ever?

It's impossible to know the exact number of chickens eaten throughout history. Here's why:

* No global records: There's no centralized record of how many chickens are raised and consumed worldwide.

* Varying consumption: Chicken consumption varies drastically across cultures and time periods. Some regions have a high per capita consumption, while others have a low one.

* Historical data: Records of chicken consumption are often incomplete or non-existent for historical periods.

However, we can look at some estimates:

* Current production: According to the Food and Agriculture Organization (FAO), the world produced around 100 billion chickens in 2020. This number is likely to have increased since then.

* Global consumption: It's safe to assume that a large majority of these chickens are consumed by humans.

* Past consumption: The number of chickens eaten in the past would be much lower, as chicken farming has become increasingly intensive in recent decades.

To summarize, while we can't know the exact number, it's clear that humans have consumed an astronomically large number of chickens throughout history.
