My dh is building a coop for my teens. He wants to put lamps in there because they are still young and he doesn't want them to freeze. The coop is divided in half (other side for my bantys for the winter). Each side is 3' x 8', low side is about 18", high side about 36". I wanted to put a red light for night but the only ones I could find were either 25w or 220w. I thought the 220 would cook them since it is insulated and I don't think the 25w will be warm enough. How do I find a solution? Here is a pic. Do they make a 100w red bulb?
