I live in the Phoenix area. I have a flock (my first ever) of 9 hens (6 different breeds). 8 of the 9 are laying. I've been getting between 6-8 eggs a day and quite suddenly my production fell off the map. We went from 6-8 to one a day yesterday and the day before. We've had two today so far at noon but usually there are more by this time of day. What could be going on? None are broody, none are molting. Btw, our post sunset lighting has not changed.
