Hi Southern By Chickens,
Yes it does sound like we are in a similar climate. We are pretty much right in the middle of the state over here. So far the lows haven't een much below freezing and are only satying that cold aout an hour out of the night. I bought a weather center thermometer that is wireless (about $14 at TS) that lets me put the sensor in with the chicks and read it from inside the house. And I am a sucker...I left the heat lamp for mine. I did order a handy dandy thermostat to plug it into, so that it will turn on and off. I just did not like the idea of it running all night. It is called an R-Zilla 1000 watt ($28)(found it on the web. It is designed for reptile cages). It will let you plug heat lamps into it, then you plug it into an extension cord, and run the temp. probe near to the heat lamp. When the heat lamp reaches the temp that you set, it cuts on or off accordingly. The girls seem completely fine, but as they had been in the basement, at 70 degrees, I just could not see pitching them out into the cold; mommy guilt! They are growing so quickly and seem very happy and perky! As this is my first go-round with chickens, I am thrilled to see them healthy and chirpy! Keep in touch and let me know how yours are doing!
