So, I tried putting a red heat lamp out there at night, in addition to the white one I have for encouraging laying. It just seemed so bright in there, that I thought it would be annoying to the hens to never have darkness. My daughter told me that chickens can't see the red light. Is this true? Also, is there a probe-type water heater that can keep the water just about 32 degrees? If so, can I put it into a plastic container. I have a hanging plastic bucket with 3 nipples in the bottom. Other than freezing, this has worked great. I crave any advice! Have a great day.
