Chickens are suitable for people living in houses with a yard.
Chickens can eat most of your kitchen food scraps in any size or shape.
Chicken manure is excellent garden food. It can be added to compost or applied directly to the garden. Home grown chicken eggs also taste delicious!
Chickens will need a predator proof shelter (something you can shut at night) with a roost and space to lay eggs, yard space to dig and scratch around and water and grain to supplement their food scraps diet.
