I have a heat lamp hung about 18 inches from the ground in my coop, I use a clamp to keep it securely in place. I just got some new babies so I needed to get it out again, but my older pullets and ducks finished with it this month, and they used it since August. I’ve had no issues. I always tug on it to make sure the clamp keeps it securely in place, and I always clear the shavings out from under it as a precaution. My pullets and ducks are pretty rowdy, but not usually at night so I feel like it’s okay.
