This is a really stupid question. How does the heat produced from a red bulb compare to that from a white bulb? The red ones are so expensive that I don't want to buy one until I have an idea what wattage will produce the correct temps. I have white bulbs that I can use in a test run. Are they the same? Has anyone used the screw in infrared heat bulbs that fit in a standard socket? How do they compare? I have 8 chicks coming from MPC in a couple of weeks (July 12 shipment date), and I want everything perfect before they come in. (new, nervous chick mommy). 20 days and counting.
