I know this has probably been answered before....here goes- I live in Reno, NV. We had a very warm fall, first freeze just a couple of weeks ago. In the past month my girls have dropped off from like 8 eggs a day to 3 or 4. I assume this is normal due to reduction in light hours and drop in temp. If I install a heat lamp that comes on for a few hours at night, could that boost it back up? My chickens are young, oldest are just 15 months old. Any tips or info would be useful. Thank you!!
