Raising a healthy flock of chickens starts with understanding their nutritional needs. Just like humans, chickens require a balanced diet of proteins, vitamins, and minerals to grow strong and thrive. For new farmers and backyard poultry keepers, navigating the different types of feed can seem daunting. This guide breaks down the essentials of chicken nutrition and explains the crucial role of different feeds at each stage of a chicken’s life.

The Building Blocks of a Healthy Diet
A balanced poultry diet is key to ensuring your chickens grow well, stay healthy, and are productive. Here are the core components:
- Protein: This is vital for growth, muscle development, and egg production. The protein requirement for chickens is highest when they are young and growing rapidly.
- Metabolizable Energy (ME): Measured in kilocalories per kilogram (Kcal/Kg), this is the energy your chickens can actually use from their feed for daily activities, growth, and staying warm.
- Vitamins and Minerals: Essential for bone formation, immune system function, and overall health. Key minerals include calcium and phosphorus, which are particularly important for strong bones.
- Fiber, Fat, and Moisture: These components are also crucial for digestion, energy storage, and hydration.

Feeding Your Flock: A Stage-by-Stage Guide
A chicken’s dietary needs change dramatically from the moment it hatches to when it’s fully grown. Using the right feed at the right time is critical for their development. LEO Feed offers a specialized range of broiler feeds to meet these changing needs: Pre-Starter, Starter, and Finisher.
1. LEO Broiler Pre-Starter 100 C: The First Crucial Days
The first few days of a chick’s life are the most critical. The Pre-Starter feed is designed to be a highly nutritious and easily digestible first food. It provides the high-energy, high-protein diet young chicks need to get a strong start in life.
- Purpose: To support rapid growth and immune system development in newly hatched chicks.
- Nutritional Profile:
- Metabolizable Energy (ME): Minimum 3100 Kcal/Kg
- Protein: Minimum 22.5%
- Calcium: 0.85% – 1.00%
- Phosphorous: 0.65% – 0.85%
- Fiber: Maximum 3.0%
2. LEO Broiler Starter 101 C: Fueling Juvenile Growth
Once the chicks are past their initial delicate phase, they transition to a Starter feed. This feed continues to support strong growth but has a slightly different nutritional balance to match the needs of a growing juvenile bird. The protein level is still high, but energy content increases to fuel their development.
- Purpose: To provide a balanced diet for the continued growth and muscle development of young chickens.
- Nutritional Profile:
- Metabolizable Energy (ME): Minimum 3150 Kcal/Kg
- Protein: Minimum 20.5%
- Calcium: 0.85%
- Phosphorous: 0.70%
- Fiber: Maximum 3.5%
3. LEO Broiler Finisher 102 P: Preparing for Maturity
The final stage of a broiler chicken’s diet is the Finisher feed. This formulation is designed to help the birds reach their ideal market weight. It is high in energy to promote weight gain and has a protein level that supports muscle maintenance rather than rapid growth.
- Purpose: To maximize weight gain efficiently as the chickens approach maturity.
- Nutritional Profile:
- Metabolizable Energy (ME): Minimum 3200 Kcal/Kg
- Protein: Minimum 20.5%
- Calcium: 0.80% – 1.20%
- Phosphorous: 0.60% – 0.80%
- Fiber: Maximum 4.0%
Providing the right feed at each life stage is the cornerstone of successful poultry farming. By understanding the specific nutritional needs of your flock—from a high-protein Pre-Starter to a high-energy Finisher—you can ensure they grow up healthy, strong, and productive.
