The Importance of Proper Nutrition

Proper nutrition is the foundation of raising healthy Cornish chicks. These birds are known for their rapid growth and high meat production, which means they have specific dietary requirements to support their growth and overall well-being. Providing the right nutrients at each stage of their development is crucial to their success.

Stages of Feeding Cornish Chicks

Feeding Cornish chicks can be divided into several stages, each with its own dietary requirements:

1. Starter Feed (0-3 Weeks)

  • Cornish chicks should start with a high-quality starter feed containing 20-24% protein. Look for feeds specifically formulated for meat birds.
  • Provide the feed in shallow dishes to make it easily accessible for the chicks.
  • Ensure a constant supply of fresh, clean water at all times. Use waterers designed for chicks to prevent drowning accidents.

2. Grower Feed (4-8 Weeks)

  • Transition to a grower feed with a protein content of around 18-20%.
  • Continue to provide access to clean water, and ensure the waterers are kept clean to prevent contamination.

3. Finisher Feed (9-16 Weeks)

  • As the chicks enter their final growth phase, switch to a finisher feed with a protein content of 16-18%.
  • Maintain good hygiene by regularly cleaning their feeding and watering equipment to prevent the spread of disease.

4. Optional Supplements

  • While high-quality commercial feeds provide most of the necessary nutrients, you can consider offering grit to help with digestion. However, this is usually unnecessary if the chicks are on a complete feed.
  • Avoid providing additional supplements unless advised by a veterinarian.

Feeding Practices

When feeding Cornish chicks, it’s essential to follow best practices to ensure their health and well-being:

1. Monitor Feed Consumption

Keep a close eye on how much the chicks are eating. Adjust the amount of feed provided to prevent overfeeding or underfeeding. Overfeeding can lead to obesity and leg problems, while underfeeding can stunt growth.

2. Limit Treats and Scraps

While it’s tempting to offer table scraps or treats, it’s best to limit these to a minimum. Too many treats can unbalance their diet and lead to health issues.

3. Provide Fresh Water

Ensure that clean, fresh water is always available. Chicks can quickly become dehydrated, especially in warm weather.

4. Prevent Cannibalism

Cornish chicks are sometimes prone to pecking at each other, which can escalate into cannibalism. Be vigilant and provide adequate space, enrichment, and distractions to minimize stress and aggression.

Housing and Environment

Apart from nutrition, the housing and environment of your Cornish chicks play a significant role in their health and development:

1. Suitable Shelter

Provide a clean, dry, and well-ventilated shelter for your chicks. Ensure that it offers protection from predators and extreme weather conditions.

2. Adequate Space

Avoid overcrowding, as it can lead to stress and health problems. Aim for at least 1 square foot of space per chick during the brooding stage and increase the space as they grow.

3. Proper Lighting

Chicks benefit from a consistent light source, which helps regulate their circadian rhythm. Provide 24 hours of light during the first week and then gradually decrease it to 16 hours of light per day.

4. Temperature Control

Maintain appropriate temperature levels in the brooder area. Start at around 95°F (35°C) and decrease the temperature by 5°F (2.8°C) each week until reaching room temperature.

Health and Disease Management

Keeping your Cornish chicks healthy is essential for their growth and eventual harvest. Here are some key tips:

1. Regular Health Checks

Monitor your chicks daily for any signs of illness or distress. Common issues to watch for include respiratory problems, leg issues, and diarrhea.

2. Quarantine New Birds

If introducing new chicks to your existing flock, quarantine them for a few weeks to prevent the spread of diseases.

3. Vaccinations and Medications

Consult with a veterinarian about vaccination programs and medications if needed. Cornish chicks can be susceptible to certain diseases, so preventive measures are crucial.

4. Biosecurity

Practice good biosecurity by limiting access to your chicks and their living area. Wash your hands and change your clothes before and after handling them to prevent disease transmission.

Harvesting Cornish Chicks

As your Cornish chicks reach their desired size and age, you may consider harvesting them for meat. The typical age for processing Cornish chicks is around 8-10 weeks, depending on the desired weight. Ensure humane and ethical processing methods are employed.


Feeding and caring for Cornish chicks requires attention to detail and a commitment to providing the right nutrition, housing, and environment. By following the guidelines outlined in this guide, you can raise healthy Cornish chicks that thrive and provide delicious, homegrown meat for your table. Remember that ongoing monitoring, cleanliness, and disease prevention are key components of successful Cornish chick rearing. With care and dedication, you can enjoy the satisfaction of raising your own poultry for a rewarding culinary experience.
