Abstract: Disclosed is a gas-fired chick brooder having an improved radiant which prevents reflector pan warpage and increases the efficiency of the brooder. The radiant comprising conventional fibrous ceramic is provided with a radial extension intermediate its lower and upper portions. The radial extension extends the radiant at least towards and in a preferred embodiment in contact with the perforated glow housing. This reduces or, in the preferred embodiment, prevents the flow of combustion gases into the region of the connection between the perforated glow housing and the reflector pan thereby preventing warpage of the reflector pan and improving the efficiency of operation.
