Raise the infrared brooder lamp about 2 inches per week until the chicks are 4 weeks old. At that time, the chicks will no longer need the lamp, but you should leave it hanging at a height of about 24 inches for the next two weeks just in case an extremely cold night is forecast. After the chicks are 6 weeks old, you can remove the brooder. The extras you ordered will leave you enough to have your flock. Clean and refill waterers daily.
Fill feeders about two-thirds full each day until the chicks are a few weeks old.
Once chicks have learned where and how to eat, half-full feeders will be adequate. Feed the chicks a 20 percent protein pullet starter diet for the first 8 weeks and a 16 percent protein pullet grower-developer diet from 8 through 20 weeks of age. Roosts can be installed after the chicks are one month old. The roosts should extend the width or length of the house. Three roosts, each about 10 feet long, should be hung about 18 inches above the floor on one side or the end of the house.
