I read many books that spoke of micromanaging the temperature in the brooder with a thermometer and using the method of raising and/or lowering the lamp in the brooder until things are just right, and continuing to do this each week. Does anyone else see this as pointless? I finally got a single bit of advice from a seasoned chicken keeper that as long as there is a warm area and a cool area in the brooder or coop (wherever they are being raised from day 1 until feathered) that they're smart enough to know when to seek the warm area and warm up, and vice versa. I found this to be true with my own girls as they've been in their coop in cold rainy WA weather since 3 weeks old, with the heat lamp in the back corner, and I've never worried that they are too cold. Is this just a preference thing or is it really a myth that they need to be heat micromanaged?
