I purchased ten feet of aluminum insulated foil from Gibson's(comes in a roll, they will cut it as long as you want it. Home Depot or Lows will have it. You can tape ends together to start for small brooder and then open up as chicks get older. Hung light from ceiling, newspaper, chips, water, feed and you have a brooder. Easy to clean and when chicks go out to pen roll up foil and store till next time, and you have your corner back. I paid about nine dollars for foil. Frankoo
Foil is two feet wide or high when standing up. It stands on its own. When chicks get older you can lay a piece of four inch bird netting over the top, It's very lite and will not bend foil. Frankoo
