I have 6 Rhode Island hens. I got 5 egges on average every day in the summer. However, I got only 1 or 2 eggs every day suddenly from last week. I don't change the feed. So I guess it may be becasue of the weather and temperature. I tried to increase the light time by a 30-watt light and used heat light (red) to increase the temperature. My question is if I keep the heat light on though the whole night, dose the red light give too much light time to the hens and affect their egg laying? Also I want to know if the temperature affect the egg laying. If not, I wan to save the power. By the way, I live in Connecticut. Thank you.
