Can You Raise Hens on a Completely Plant-Based Diet?

April 5, 2026

Quick Answer

While it's possible to raise hens on a plant-based diet, it can be challenging to provide them with all the necessary nutrients, and egg production may decline.

Nutritional Requirements

Hens require a balanced diet that includes protein, calcium, and other essential nutrients to maintain their health and produce eggs. A plant-based diet can be supplemented with commercial feed or homemade alternatives, but it must be carefully formulated to meet their nutritional needs. For example, a hen requires about 1 gram of calcium per egg produced, and plant-based sources like alfalfa, kelp meal, or crushed eggshells can provide this essential nutrient.

Commercial Plant-Based Feed Options

There are several commercial plant-based feed options available for egg-laying hens, such as Purina’s Organic Layer Feed or Manna Pro’s Layer Feed. These feeds are specifically formulated to meet the nutritional needs of hens and can be used as a primary source of nutrition or as a supplement to a homemade diet. It’s essential to choose a feed that is free from animal products and by-products to ensure that the hens are fed a truly plant-based diet.

Homemade Feed Formulation

For those who prefer to create their own homemade feed, a combination of grains, legumes, and vegetables can provide the necessary nutrients. For example, a recipe might include 50% whole grains like oats, barley, or wheat, 20% legumes like soybeans, lentils, or chickpeas, and 30% vegetables like alfalfa, kelp, or broccoli. The feed should be formulated to provide the necessary protein, calcium, and other essential nutrients, and it’s recommended to consult with a veterinarian or poultry expert to ensure that the homemade feed meets the hens’ nutritional needs.
