I am trying to heat my coop, but I am afraid this infared bulb is causing too much heat. My coop is small, 2ft x 3ft x 3ft. My main reason for wanting to heat my coop is mainly because I am trying to lurrer my chickens into their house at night. They currently insist on sleeping on the ground in their run, which is not safe and is super cold. I was thinking that if I put heat in the coop they will want to go in at night. Any suggestions? Also, is my wooden coop going to catch fire with the hot bulb? Thanks!
