Oh - I have a remote thermometer so I can tell exactly what the temp is in each corner or right underneath the bulb, wherever! It's got a little rectangular thing that reads the temp, then it transmits it to the reciever up to 300feet away! I've been playing around with it and it seems like there's almost a 10 degree difference between right under the light and about 2 feet away, so I think the chicks should be able to get warm when they want, and get away from the heat also.... I'm planning to mount the thermometer part outside once we move them out to the coop, so I can keep a good eye on the temp in the coop - winter and summer! I wonder where I could get a red screen thingy... Aren't they called gells in the theatre business? I need to check on those!
