My hens have all started laying now. I'm averaging 7 eggs per day from 9 hens. The heat here in Oklahoma has diminished and we are now getting some low night temps in the 50's and high day temps in the 80's & 90's. At what point will they slack off for the winter? I know I may still get an egg here or there, but when will I notice that they've went in to hibernation, so to speak? My plan is to keep things natural, meaning no artificial light. Thanks in advance.
