It' is going to be below 0 here in MT for a couple of days and I wanted to provide our red sex links with a little extra heat at night. I am using a red heat light that I used for them as chicks, but I am concerned that this kind of light might effect their internal clocks. I have read not to give them more than fourteen hours of light. Does anybody know if this red light effects their sleep and egg laying habits? Your help is always appreciated.
