Chicken manure is primarily used as a potent, nutrient-rich organic fertilizer for gardens, crops, and grasslands, providing essential nitrogen for leafy growth, plus phosphorus and potassium for roots, flowers, and fruits, but it must be composted first to prevent burning plants and killing pathogens like Salmonella, transforming it from a strong, fresh product into a safe, soil-enriching soil amendment. It’s sold dried and pelleted for convenience or composted from coop litter for various applications.
