There are many different types of feed formulas for poultry, and the specific formula you use will depend on the age and type of poultry you are feeding. However, a basic poultry feed formula typically contains a mixture of grains, protein sources, and minerals. Here is an example of a basic poultry feed formula:

• 60% corn
• 20% soybean meal
• 10% wheat
• 5% fish meal
• 3% oyster shell or limestone
• 2% vitamin and mineral premix

Note that this formula is just an example, and you may need to adjust the amounts of each ingredient based on the specific needs of your flock. Additionally, it’s important to ensure that the feed you use is nutritionally balanced and free from contaminants.
