Comprehensive Nutrition and Diet Guide for Chickens

 

Like all animals, chickens need various nutrients to stay healthy. These nutrients can be divided into six main categories:

• Proteins
• Carbohydrates
• Fats
• Vitamins
• Minerals
• Water

Proteins

Proteins are vital for growth, feather development, and egg production. They are made up of amino acids, the building blocks of body tissues. Chickens, especially young chicks, and laying hens, require a diet high in protein.

Protein sources are commercial feeds, fish meal, soybean meal, mealworms, and other insects.

Protein Requirements:

• Chicks: 20-24% protein
• Growing pullets: 16-18% protein
• Laying hens: 16-18% protein

Carbohydrates

Carbohydrates provide chickens with the energy they need for daily activities. They are found primarily in grains and are essential to a chicken’s diet.

Corn, wheat, barley, oats, and other grains are sources of carbohydrates.

Carbohydrates should make up a significant portion of the diet, especially for active and free-ranging chickens.
