Small Farm Animals That Eat Grass . Get some of that before you start! The essential thing you will need for farming is food for the animals.
Chickens require a covered area to stay dry, fresh water, and a place to nest and lay their eggs. 3 cows will demolish 25,000 sq feet of grass in one day. Some of these animals are mice, rats, rabbits, geese, and guinea pigs.
A single guinea pig can eat five times its bodyweight of grass a day.
Get some of that before you start! Chickens eat seeds (most easily obtained from wheat or long grass, but they will eat any kind of seed, such as pumpkin or melon seeds). These species are the malayan tapir, mountain tapir, brazilian or south american tapir, and baird’s tapir. Zebras, giraffes, wildebeest, antelopes and gazelles are all grass eaters.
