I have 12 Australorp ladies, 1 1/2 years old, and up until to the last few weeks at molt they were great layers... Over the last 6 weeks, they've gone from 10 eggs per day, to 7, to 6, and only two for the last two weeks. Tonight, no eggs at all. They've finished their molt, food is good with scraps from the house, but they've just completely quit now. I keep them wormed, and comfortable in their coop at night. Weather has been warm except for recent high winds which may have disturbed them, but still, the gradual decrease over several weeks is puzzling. Any suggestions?
