Raise newborn chicks in a heated brooder and feed them chick crumbles, which can be purchased from a local farm supply store or online. When they are about 2 months old, move the chickens to an outdoor coop and feed them formulated pellets.
First, make sure that raising backyard chickens is legal under zoning regulations in your area. Purchase newborn chicks online or from a local feed mill. Getting the chicks when they are just a few days old allows them to establish a pecking order and grow up accustomed to humans.
For the first few weeks of your chicks' lives, keep them in a brooder equipped with food and water dispensers and a heat lamp. Maintain a temperature of 90 to 100 degrees Fahrenheit, and decrease the temperature by 5 degrees each week. When they are 2 months old, move chickens to an outdoor coop. Allow 2 square feet per chicken inside the coop and 8 to 10 square feet of yard outside for chickens to stretch their wings and to socialize with one another. Make sure the coop is properly ventilated and safeguarded against predators.
Ensure chickens have an adequate supply of food and water each day. Line the inside of the chicken coop with pine shavings, and replace the lining regularly. Secure chickens inside the coop at night.
