Royal Purple Guinea Fowl are omnivorous foragers whose natural diet consists primarily of insects, seeds, vegetation, and occasional small invertebrates. In free-range situations, these birds obtain much of their nutritional needs through intensive foraging, consuming thousands of insects daily including ticks, grasshoppers, beetles, spiders, and various larvae. This natural feeding behavior reduces supplemental feed requirements while providing valuable pest control services. However, even free-ranging guineas benefit from supplemental feeding to ensure complete nutrition.
Commercial game bird feed or turkey starter provides appropriate nutrition for keets from hatch through 8 weeks, offering the higher protein levels young guineas require. Starter feeds should contain 24-28% protein to support rapid growth and feather development. After 8 weeks, birds can transition to grower feed with 18-20% protein until 16-20 weeks of age. Adult maintenance feed can be either game bird maintenance formulas, turkey feed, or standard chicken layer feed, though non-layer formulas are preferable for non-laying males and off-season hens since excessive calcium can cause kidney issues in birds not actively producing eggs.
Seasonal laying hens require calcium supplementation during egg production periods. Offering crushed oyster shell or similar calcium sources free-choice allows hens to consume what they need for strong eggshell formation. Guinea eggs have notably thick shells requiring adequate calcium availability. However, males and non-laying hens should not be force-fed high-calcium layer feeds continuously. Grit is essential for guineas to grind food in their gizzards - both soluble oyster shell grit (calcium) and insoluble granite grit should be available free-choice.
Water requirements remain consistently high, especially in warm weather and during laying periods. Clean, fresh water must be available at all times in containers appropriate for guinea fowl. These birds prefer open water dishes or large poultry waterers rather than small containers. Water consumption increases during hot weather and when consuming dry feeds. Containers should be cleaned regularly to prevent contamination and algae growth. In winter, preventing water from freezing requires heated waterers or frequent water changes.
Supplemental treats and foraging opportunities enhance nutrition and natural behavior. Safe treats include mealworms, scratch grains (in moderation), leafy greens, and vegetables. However, guineas are excellent foragers and shouldn't become dependent on treats, which can interfere with natural pest control activities. Avoid feeding foods toxic to poultry such as chocolate, avocado, dried beans, moldy feeds, or excessive salt. Most guineas ignore commercial scratch grains when insects are available, demonstrating their strong preference for protein-rich natural foods over simple carbohydrates.
