I'm interested in formulating my own quail feed to reduce costs and ensure optimal nutrition for my birds. While I understand the importance of providing a balanced diet, I'm unsure about the specific nutrient requirements of quails and the best sources of these nutrients. What are the essential nutrients required in a quail diet, and in what proportions?

What are some readily available and cost-effective ingredients that can be used to create a balanced and nutritious quail feed? I need a detailed recipe or formula, including the quantities of each ingredient, and guidance on mixing and storage techniques to maintain feed quality and prevent spoilage. Information on the potential risks of nutritional deficiencies and how to recognize their symptoms in quails would also be helpful.
