The world of poultry nutrition is both fascinating and essential for raising healthy chickens. In her impressive capstone project, student Naomi Duehr delves into the nutritional requirements of chickens. She is developing a chicken feed tester that will help identify the best foods for these birds. The sources range from proteins and grains to calcium, vitamins, and supplements. Through thorough research and experimentation, Naomi aims to create a feed recipe that meets the nutritional needs of chickens while also being tasty for them.
Naomi’s journey into chicken nutrition stems from her desire to understand what constitutes a healthy diet for these birds. Chickens are known for their dietary flexibility and can thrive on various foods. However, finding the right balance is crucial. The main components they require include grains, proteins, calcium, and specific vitamins, all of which play unique roles in their growth and egg production.
Understanding Chicken Nutrition
Understanding the basic dietary needs of chickens is crucial. Chickens primarily require a diet rich in carbohydrates, protein, fats, vitamins, and minerals.
Carbohydrates and Grains
Carbohydrates are key for chickens, providing the energy necessary for daily activities. Common carbohydrate sources in chicken feed include corn, wheat, and barley.
Naomi highlights these grains in her research, stating they form a solid foundation for any chicken feed recipe. For instance, corn, which makes up about 50% of many commercial chicken feeds, is praised for its high energy content.

Protein Sources
Proteins are vital for growth, muscle development, and overall chicken health. Protein sources can range from plant-based options to animal protein, such as soybean meal, which contains about 44% protein.
In her project, Naomi investigates the correct amounts of these proteins to ensure chickens receive adequate nutrition. By measuring the protein content in various feed types, she aims to uncover the best combinations for a healthy diet. Her goal is to ensure that each chicken receives around 16-18% protein, which is critical for optimal growth.
Calcium and Its Importance
Calcium is another essential nutrient, especially for laying hens, who need it for strong eggshell production. Common sources of calcium include limestone and ground oyster shells.
Excitingly, Naomi’s research also examines the use of crushed eggshells as a natural calcium supplement. This approach not only recycles waste but ensures chickens receive the necessary calcium for healthy egg production. In fact, providing around 3-4% calcium in their diet can lead to improved eggshell quality.
Vitamins and Supplements
Beyond carbohydrates, proteins, and calcium, vitamins play a crucial role in chicken nutrition. Vitamins like B12, A, and D are essential for growth, immune function, and overall health.
Naomi is conducting an in-depth analysis of the necessary vitamins in chicken feed and how to incorporate them effectively. She is also considering adding probiotics, which can aid in chickens' digestive health and enhance nutrient absorption. These additions could result in weight gains of up to 10%.
Recipe Development
As her project progresses, Naomi's primary goal is to create a balanced recipe that fulfills all nutritional needs while being enjoyable for the chickens.
She plans to mix the grains, protein sources, calcium, and essential vitamins into a feed that her mentor, Mrs. Schriver, will test with the chickens. By observing the chickens’ preferences and health, Naomi hopes to refine her recipe for optimal results.
The Importance of Practical Testing
One of the most exciting aspects of Naomi's project is the hands-on testing phase. By recording how different recipes affect the chickens' health and behavior, she will gather valuable insights.
The results of her experiments will help identify which foods the chickens thrive on and which combinations are most effective. This practical approach strengthens her findings and provides important implications for chicken owners seeking to ensure the best possible nutrition for their flock.

Final Thoughts and Future Implications
Naomi Duehr’s capstone project is much more than an academic exercise; it underscores the importance of understanding bird nutrition. Chickens play a major role in agriculture, contributing to food systems and livelihoods worldwide. By concentrating on chicken nutritional needs, Naomi's research has the potential to improve the health and productivity of poultry flocks.
With her final recipe, Naomi aims not only to cater to the taste preferences of chickens but also to promote a broader understanding of proper chicken care. As her project unfolds, it will serve as a great resource for small-scale farmers and poultry enthusiasts alike, paving the way for healthier and happier chickens.
Naomi’s passion for poultry nutrition and her commitment to developing an effective feed recipe are commendable. As she prepares to share her findings, it will be exciting to see how her research impacts chicken owners in the long run.
In summary, Naomi's capstone project is an inspiring example of how focused research can lead to tangible improvements in poultry care. Her work emphasizes the significance of nutrition for chickens and highlights a sustainable approach to feeding. By incorporating her findings into real-world applications, Naomi is providing valuable insights into animal husbandry. As we continue to understand the needs of our feathered friends, projects like Naomi’s will help shape a healthier future for chickens everywhere.
Additionally, this project illustrates the profound connection between nutrition and chicken productivity, promoting comprehensive resources that help maintain healthy livestock. It emphasizes how informed decisions can improve poultry health and well-being.
Feel free to explore more about the intricacies of poultry nutrition by understanding its various elements such as proteins, vitamins, and supplements. It's a journey toward improving overall flock health.
With Naomi's insights, the future looks bright for poultry nutrition enthusiasts and chicken farmers alike.
What a great project and article that actively contributed to a healthier food system and showcases all of the science skills and writing talent for others to appreciate! Great job!
I can't wait to see the final results
