hi all i'm an engineering atudent tasked with designing a fully programable chicken feeder. the device should automatically feed the animals twice a day, and must function without human intervention for a week, so it must also store the required amount of food for a week. ideally, i'd like to design a device to be used on an intensive chicken farm. but i have no knowledge about chicken farming at all. hopefully you could answer a few questions of mine. how much does a chicken eat per day, and what sort of numbers are there on an intensive chicken farm. also, what exactly are these chickens fed? any advice would be greatly appreciated. thank you.
