So last year when I bought chicks I bought a regular clear heat lamp because I couldn't find a red one. This year I found a red one...YIPEE!! Whelp, I get it home, put it in, get the chicks warmed up and look at the box and it's an infrared red heat lamp. Sooooo, my question is, what's the difference (if any) between an infrared bulb and a red bulb? Thanks guys!
