Chicken feed is not unsafe or harmful for peacocks but does not contain enough protein for peacocks, so it is not recommended to feed peacocks with chicken feed.
Peacocks need 25%-30% crude proteins in their diet, depending on their age. Baby peacocks need 30% or more crude proteins in their diet if you want them to grow quickly and be healthy.
“Formulated feed” means nutrient-rich pellets for your peacocks. You can buy peacock pellets from feed mills or pet shops.
Peacocks love their grains and seeds, so you want to give them as treats. Do not give your peacocks too many grains, as grains are richer in carbohydrates than in proteins.
Peacocks love their vegetables and fruits. Vegetables and fruits have a lot of nutrients for your peacocks, and they are also delicious to these birds.
