A poultry farm hen will usually require a balanced diet of grains, proteins, and vitamins and minerals. They should be fed a grain-based diet that is supplemented with proteins such as fish meal, soybean meal, or other animal proteins. The grain should be provided in the form of pellets or crumbles. Vitamins and minerals should also be added to the diet to ensure the hens receive the necessary nutrients. Fresh water should also be available at all times. It is important to regularly check the diet and adjust as necessary to ensure the hens are receiving a balanced diet.
