Best Phosphorus-Rich Foods for Chickens

Ranked by phosphorus content among foods safe for chickens in the Creature Feast catalog.

Lentils per 100g cooked: 180mg phosphorus Lentils are among the richest plant sources of phosphorus available to chickens. Unlike grains where most phosphorus is locked in phytate and poorly absorbed, a significant portion of lentil phosphorus is available. Cooking further improves digestibility and phosphorus release.

Sunflower Seeds per 100g: 660mg total phosphorus Sunflower seeds contain substantial phosphorus, though a portion is bound as phytate. For chickens, the overall phosphorus delivery is still meaningful, and the seeds' fat and protein content make them a nutrient-dense supplement that supports multiple nutritional needs simultaneously.

Oats per 100g dry: 410mg total phosphorus Oats provide a moderate phosphorus contribution alongside their protein and fiber benefits. The phosphorus in oats is partially phytate-bound, but the overall nutritional package makes oats a valuable supplement for flock health when fed as a warm mash or dry.

Peas per 100g: 108mg phosphorus Green peas deliver readily available phosphorus in a form that chickens digest well. Fresh or thawed frozen peas are eagerly pecked up by most flocks and provide phosphorus without the high phytate levels found in many cereal grains.

Barley per 100g dry: 264mg total phosphorus (limited availability) Barley contains moderate phosphorus levels, though much of it is phytate-bound and has limited bioavailability in poultry without phytase supplementation. Sprouting barley for a few days can activate endogenous phytase, significantly improving phosphorus availability for the flock.
