There are two ways to start when it comes to raising chickens. First you can start with hatching eggs and an incubator.
This method is more involved as it requires more equipment and takes considerably more time and attention. The approximate incubation period of a chicken is 21 days and eggs need to be turned at least 3 times a day unless you have an automatic egg turner. Temperatures in the incubator must be closely monitored as well. Most quality incubators will have a thermostat controlled heat source.
If you decide to start with hatching eggs, you can expect hatching eggs to start at around $5 for a dozen eggs of a common breed of chicken. If you want to purchase hatching eggs from a more exotic breed, you can spend up to $5 per egg.
Incubators start out at about $50 for a basic model and go as high as $1000 for a more advanced high capacity model with automatic turners, temperature and humidity controls. An egg incubator that holds about 4 dozen eggs with automatic turner and thermostat controlled heater will run about $200.
Until they are incubated, hatching eggs should be stored in cartons or cases—large end up at 50 to 60° F. with a relative humidity of about 75 percent. If the eggs are to be stored for more than 2 to 3 days before they are incubated, their positions should be changed each day to reduce the tendency for the yolks to stick to the shells.
A large selection of hatching eggs and incubators can be found here. After you purchase your eggs, please follow the directions that come with your incubator for best results.
Once your chicks hatch, go here and follow the directions for starting with day old chicks.
