It's not as complicated as it seems. With my first batch of chicks years ago I was constantly checking the temperature in the brooder & moving the heat lamp to have the perfect temperature. Temperatures in the brooder do not have to be exact, but close is good..
Start the temperature at 98 degrees for the first day only, lowering it to 95 degrees on day two, then lower it 5 degrees each week until reaching 70 degrees. By then most chicks will also be feathered out & able to hold their own body heat.
You will need a large plastic bin, large box, or feeding troth for your chicks first home. I prefer to have the sides of the brooder at least 24" tall because by the time they are 2 to 3 weeks old many will be able to fly out.
I find that pine flakes work best for a bedding. But don't use shavings because they are too small & the chicks will try to eat them. I put paper towels down over the bedding for the first two days and sprinkle chick feed on them. This works best until they all figure out the difference between the bedding and the food. You will need feeders for water & feed, and a heat lamp or a heat pad to keep them warm.
