What is the sickles of a chicken?

Sickles are the long, curved feathers that grow from the rooster's back and curve over its tail. They are a prominent feature of male chickens and are often seen as a sign of dominance and attractiveness to hens.

Here's why you might be confused:

* Chickens is a general term that refers to both male and female birds.

* Roosters are adult male chickens.

* Hens are adult female chickens.

So, while a chicken can refer to either a male or female bird, sickles are specifically a feature of roosters.
