OK.. I'm in the process of building my coop. I'm going to be having about 10 chickens. I'm going to be keeping them in our sunroom. It has no air or heating, so I'm going to have a heat lamp for them. However, the temps will fluctuate. I live in AL, so our day temps are going to be fluctuating between 55 and 75 degrees til about May. Our night temps are still low, fluctuating between 25 and 45. Will start to warm up in April. I keep reading that chicks have to be kept at 100 degrees, then 95 degrees, then 90, so on and so forth.. How do I do this with fluctuating temperatures? Our sunroom's temperature always varies 2 to 4 degrees. I want to make sure I do this right.. I've never had chickens.
