Explain the feature in as much detail as possible

Guineafowl could be a new bird added. Unlike animals such as chickens, they’d be neutral, and would mob threats once found. As a result, they could be used as guard animals.

They like to perch in trees, even though their wings can be clipped for a bit using shears.

By default, wild ones would spawn in savannas.

Perhaps add a few breeds as well?
