Best Zinc-Rich Foods for Chickens

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

Sunflower Seeds per 100g: 5.3mg zinc Sunflower seeds are one of the richest zinc sources among chicken-safe treats. Zinc is critical for feather development, immune function, and wound healing in poultry, and deficiency causes the characteristic frayed feathers and skin lesions that backyard keepers sometimes mistake for mite damage.

Lentils per 100g cooked: 1.3mg zinc Lentils provide a solid zinc contribution alongside their protein and iron benefits. For laying hens, adequate zinc supports both eggshell quality through its role in carbonic anhydrase enzyme activity and immune resilience during the stress of daily egg production.

Oats per 100g dry: 3.6mg zinc Oats contain moderate zinc, and while some is phytate-bound, the overall zinc delivery from oats supports the feather keratin synthesis and immune function that laying hens depend on. Soaking oats before feeding can improve mineral availability.

Peas per 100g: 1.2mg zinc Peas provide a modest but bioavailable zinc contribution. Their lower phytate content compared to cereal grains means a higher percentage of the zinc actually reaches the chicken's intestinal absorption sites, making peas a more efficient zinc source per milligram than many grains.
