we recently got some chicks from McMurray, I had been using a regular light bulb in the brooder for heat, then someone told me that we should be using a red infared bulb instead. So I bought one. Thing is that the chicks seem to be acting different. My kids think that the red light is wacking them out. (the chicks) They seem to be not as active but the temp is the same as what I kept them at with the regular bulb. Anyone have any suggestions?
