I have a brooder heater that is approximately 33 inches long for sale it is thermostat controlled the knob is missing . it would be good for a small brooder box. you can hook chains to it to hang down to adjust the height. There is a red light and a whit light on it. red light goes out when temp is reached in the brooder and the white light stays on so the chicks can see to eat and drink. 65.00 shipping included
