The Buckeye rooster is a surprising addition to this list.

For some reason, this breed hasn’t let go of its ancestors’ wild and aggressive genes.

If it is your first time keeping chickens and roosters, we recommend erring on the side of caution and incorporating a more docile and manageable breed into your flock.

Why Keep An Aggressive Rooster?
If you’ve ever encountered an aggressive rooster or had to deal with a particularly nasty fight, you may wonder why you would ever want an aggressive rooster in the first place.
There are a few reasons why you’d want this.
Most aggressive chickens require a lot of space and don’t do well in confined spaces.
For this reason, it is incredibly important to make sure you have enough space for the often athletic and large breeds on this list.
While cockfighting is illegal in many places, there is still some popularity in certain parts of the world.
It makes sense to want the most aggressive rooster possible if you consider cockfights.
Many of these aggressive chickens also tend to be tall, muscular, and athletic, making them excellent fighters.
However, the business of cockfighting has lost significant popularity over the past century.
There aren’t many people specifically breeding for cockfighting nowadays.
Guard The Flock
A much more common reason for keeping an aggressive rooster is to guard the flock.
By nature, roosters have the instincts to protect their territory and their flock from any threats.
This is especially beneficial if you live in an area with pesky predators like foxes, possums, and raccoons.
While your rooster may not be able to fight off all threats, they will certainly give it their all when it comes to protecting their hens.
Many aggressive rooster breeds tend to have a natural inclination towards protection.
While this may make egg collection and feeding time a bit of a hassle, it may be worth it if your flock is under threat from predators.
They will also make a ruckus when fending off predators, which gives you extra time to get rid of them before they get to your hens or their eggs.
