The Guinea fowl we know here in Australia is the Helmeted Guinea fowl (Numida meleagris). There are two other species not found in Australia to our knowledge: the Crested Guinea fowl (Guttera pucherani) and the Vulturine Guinea fowl (Acryllium vulturinum).
The colours we know of in Australia—and have bred—are:
pearl grey (the original wild type grey colour with white dots (called “pearling”)); lavender (like pearl grey but lighter); silver; cinnamon, and white.
In addition there are three body patterns.
Guinea fowl are low maintenance and very hardy birds, but like anything, a bit of care and attention from you will go a long way in their welfare. Keets (Guinea fowl chicks) can be taken to their new homes from 4 weeks of age when they are fully fledged.
