While we raise layers for their eggs (and the delicious stewing hens we get when laying days are over), the natural life of a chicken serves many purposes on the farm.
Domestic chickens are descended from jungle fowl so their natural diet is insects, plants, small rodents, lizards and seeds. A "vegetarian" diet is actually not a complete and healthy diet for a chicken. We are grateful for the labor-saving joy these chickens are experiencing. They'll be happy when we share the extra berries with them next year too!
The patch of soil the chickens are rehabilitating is on an area that is part of what was the most worn out of our pastures when we bought the farm 4 years ago. For 4 years we have bush-hogged whatever grew and allowed the plant life to lie on the soil to decompose. For 3 years chickens have been moved across the pasture from one spot to another and we can see the benefit of our efforts. No pesticides, insecticides or herbicides have been used on any part of the farm and the land is healing. As the land heals the plant life changes from weeds to grasses, eroded places vanish as the increasing organic matter in the land enables the soil to absorb the water.
