Best Magnesium-Rich Foods for Chickens

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

Sunflower Seeds per 100g: 325mg magnesium Sunflower seeds are among the richest magnesium sources in the chicken treat pantry. Magnesium supports over 300 enzymatic reactions in the hen's body, including the eggshell calcification process where it helps regulate calcium deposition in the shell gland.

Lentils per 100g cooked: 36mg magnesium Lentils deliver excellent magnesium alongside their protein and mineral profile. For laying hens, this magnesium supports the muscle contractions of the oviduct that move the developing egg through the reproductive tract, from ovulation to lay.

Spinach per 100g raw: 79mg magnesium Spinach is a concentrated magnesium source, and unlike its calcium, spinach magnesium is well absorbed by chickens. The magnesium supports nerve and muscle function throughout the flock, helping prevent the leg weakness and tremors associated with deficiency.

Oats per 100g dry: 138mg magnesium Oats provide reliable magnesium in a form chickens readily consume. A warm oat mash in winter delivers magnesium alongside energy and protein, supporting the metabolic processes that keep hens warm and productive during cold months.
