I have 2 hens and the inside of my coop has just enough room for the girls to lay and sleep and move around. And I have been looking around and researching the heat lamps. However, at the farm store all they have is a 250 watt bulb. I'm just afraid that is way to hot. I have used a bulb and put a trouble cover it. The girls loved it. But then they started playing with it. HELP!?!
