Best Manganese-Rich Foods for Chickens

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

Oats per 100g dry: 4.9mg manganese Oats are among the best manganese sources for chickens, and manganese is critical for eggshell quality. Manganese activates the enzymes that build the organic protein matrix of the shell, the structural scaffolding onto which calcium carbonate crystals deposit.

Barley per 100g dry: 1.9mg manganese Barley provides excellent manganese and supports the shell matrix formation that keeps eggshells smooth and structurally sound. Rough, pimpled, or chalky eggshells can indicate manganese deficiency even when calcium is abundant.

Spinach per 100g raw: 0.9mg manganese Spinach provides notable manganese alongside its other mineral content. In laying hens, this manganese supports both the eggshell matrix and the cartilage integrity in leg joints that bear the strain of the hen's daily activities.

Lentils per 100g cooked: 0.5mg manganese Lentils provide moderate manganese in a bioavailable form. For growing chicks, adequate manganese prevents perosis (slipped tendon), one of the classic poultry nutritional diseases that causes permanent crippling if not caught early.
