My 15 hens were laying 9-12 eggs a day for over a week not I get 3-5 eggs a day. It was a sudden drop - one day lots of eggs, the next day 3. The weird thing is that the weather has warmed up here and I expected there to be plenty of eggs. I haven't changed feed, there's nothing stressing them that I can tell. Not molting. Droppings seem pretty normal. Does anyone have advice?
