You can use a large cardboard box, bathtub, or large plastic Tote for a few days as a brooder. Many feed stores use the 50 gallon metal stock tanks, with a heat lumped clamped. I bought some play wood and built a brooder 4 feet long, 2 feet wide, and 2 feet tall. After a week, the top needs to be covered with screen wire or 1/2 hardware cloth screen because they will learn to jump out. You can make a wound frame for the screen wire.
You need bedding, pine shavings, or you can use layers of paper towel for a week or so. A heat lamp should be secured carefully 18-24 inches from the top of heads. Have one end of the brooder at the warmer temperature under the heat lamp. The other end can be a bit cooler.
Dip your chicks’ beak into the food and water. Chick starter is what to feed. Do some reading on how to raise chicks. They will all die if you don’t heat them.
