If you’ve lived around guinea fowl, then you can attest to the fact that they are very noisy.Guinea fowl are typically raised for biological control of pests, as well as for meat and egg production.
Keeping guinea hens quiet is a bit difficult, but it is not impossible. They are one of the least intelligent birds, so they make noise when they experience any external stimulus, even harmless ones.
Guinea fowl can be frustratingly noisy for their owners. Understanding why they make a ruckus in the first place can help you manage the noise later on.
