Introduction: Understanding the Growth Stages from Chicks to Laying Hens
Laying hens are the backbone of egg production in the poultry industry, and their journey from fragile chicks to productive layers is critical for any layer farmer. Whether you’re an experienced farmer or just starting out, understanding the different growth stages from chicks to laying hens is key to maintaining a healthy flock and maximizing egg production. This article will guide you through each stage of development, offering practical tips on nutrition, housing, and management to ensure your hens thrive. Let’s dive into the essential phases of a hen’s life cycle and explore how to navigate each one effectively.
Why Understanding the Growth Cycle is Critical for Layer Farmers
Each stage of a hen’s growth plays a vital role in determining the overall productivity and health of your flock. Without a solid grasp of how chicks develop into laying hens, farmers risk poor egg production, health issues, and unnecessary costs. Proper management of each stage ensures that hens are not only laying efficiently but also remain healthy throughout their lifespan. Understanding the unique needs at each growth phase will help you make informed decisions that optimize nutrition, housing, and disease prevention, which are crucial for your flock’s success.

The Role of Each Stage in Egg Production and Poultry Health
The journey from chick to laying hen involves several distinct stages: brooding, growing, pre-lay, and laying. Each stage requires specific management practices, including changes in feed, environment, and health care. By following the natural growth stages of hens, you can ensure they develop into robust layers, capable of producing high-quality eggs. Let’s explore these stages in more detail.
Stage 1: The Brooding Stage (1 to 6 Weeks)
What is the Brooding Stage?
The brooding stage is the critical first phase in the life of a chick. It typically lasts from birth until the chick is around six weeks old. During this period, chicks are vulnerable to temperature changes, diseases, and nutritional deficiencies. Proper brooding management is essential for survival and future productivity.

Ideal Conditions for Raising Healthy Chicks
To raise healthy chicks, temperature, lighting, and ventilation must be carefully controlled. For the first week, the brooder should be kept at about 95°F (35°C), gradually reducing by 5°F each week until the chicks are fully feathered. Adequate lighting is essential, as it helps chicks find food and water while promoting normal growth.
- Temperature: Consistent warmth ensures proper metabolism and prevents chilling.
- Lighting: Chicks need 24 hours of light for the first week, then reduced to 16-18 hours daily.
- Ventilation: Fresh air is crucial for reducing ammonia buildup and maintaining respiratory health.
Nutrition Requirements for Chicks
Chicks have high nutritional needs for rapid growth. A protein-rich diet is essential during this stage, with starter feed containing at least 18-20% protein. Key supplements like vitamins and minerals, especially calcium and phosphorus, promote strong bones and immune system development.
- Protein-Rich Diet: Essential for muscle and tissue development.
- Supplements: Ensure chicks get adequate calcium and phosphorus for skeletal health.

Common Challenges and Solutions in the Brooding Stage
Chick mortality and growth deficiencies are common issues in brooding. Keeping the environment clean, dry, and warm is crucial. Regularly check for signs of disease, dehydration, or nutritional deficiencies, and address them promptly.
Stage 2: The Growing Stage (7 to 16 Weeks)
Transitioning from Chick to Pullets
As chicks grow into pullets, their nutritional and environmental needs change. This stage is marked by rapid growth, and proper management is essential for developing strong, healthy pullets ready to begin laying.

Growth Milestones and Expected Body Weight
Pullets should achieve around 75% of their adult weight by the end of the growing stage. Monitor growth regularly to ensure they meet expected weight targets. A balanced diet and good management practices will help you avoid underweight or overweight birds, both of which can impact egg production later.
Nutritional Needs for Growing Pullets
The focus during this stage is on bone and muscle development. Pullets should transition from high-protein starter feed to grower feed, which typically contains around 16-18% protein.
- Shifting from Starter Feed to Grower Feed: As protein requirements decrease, energy needs increase to support growth.
- Calcium Supplements: Begin to introduce small amounts of calcium as pullets approach the pre-lay stage.
Housing and Environmental Management for Pullets
Pullets need more space as they grow. Ensure that their housing provides ample room, good ventilation, and proper sanitation. Overcrowding can lead to stress and disease, so monitor space requirements carefully.

How to Avoid Common Mistakes in the Growing Stage
One common mistake is failing to adjust feed and housing as pullets grow. Make sure to provide adequate nutrients and space to avoid stunted growth and prevent issues like pecking and aggression.
Stage 3: The Pre-Lay Stage (17 to 20 Weeks)
What Happens in the Pre-Lay Period?
The pre-lay stage marks the transition from pullet to laying hen. At around 17 to 20 weeks, pullets begin preparing for egg production. Their behavior, diet, and environmental needs change during this time.

Nutritional Adjustments to Prepare for Laying
This stage requires increased calcium and phosphorus to support eggshell production. Switch to layer feed, which is specially formulated to provide the nutrients needed for laying hens.
- The Importance of Calcium and Phosphorus in Diet: These minerals are vital for eggshell formation and bone health.
Behavioral Changes to Watch For
Pullets may become more active and begin exploring nesting areas. Monitor for signs of aggression, as overcrowding can cause stress.

Preparing Housing for the Onset of Laying
Ensure that nesting boxes are clean, dry, and accessible. Pullets should have easy access to nesting areas to prevent laying eggs on the floor, which can lead to contamination.
Stage 4:The Laying Stage (20+ Weeks)
Understanding the Onset of Egg Production
At around 20 weeks, hens begin laying eggs. The quality and quantity of egg production depend on how well they’ve been managed in earlier stages.

Nutritional Needs for Laying Hens
The diet of laying hens should be high in calcium and balanced in protein. Layer feed is specially formulated to meet these requirements, containing about 16% protein and an appropriate calcium level for eggshell production.
- The Role of Layer Feed and Calcium Supplements: Ensure hens receive the right amount of calcium to avoid eggshell defects.
Housing and Nesting Requirements for Optimal Egg Production
Nesting boxes should be clean, comfortable, and well-ventilated. Hens need adequate space and a stress-free environment to produce high-quality eggs.
Common Health Issues in Laying Hens and How to Address Them
Monitor hens for signs of disease, including respiratory infections and egg-binding. Regular health checks and vaccinations are essential for preventing outbreaks.
