I had been collecting as many as 7 eggs a day from my little flock of 7 1 year old Buff Orpingtons and gold laced Wyandottes. Over the last two or three weeks, production has dropped to as few as 3 or 4 eggs a day, and once, only 2! I keep their coop clean, provide plenty of fresh water and invest in good feed. I generally give them a good handfull of scratch when I open their coop in the morning, and they love an occasional treat of yogurt or fresh corn. they are not free-ranged, as we have a red hawk and quite a few owls in the area. I have a neighbor down the road who has lost 3 chickens to the red hawk! They have an ample space under their 4' by 8' coop, and it's attached to a 4' by 8' covered run. I have also added calcium-oyster shell to their feed in the recommended amounts. I "dust' with diatomaceous earth when I clean the coop. It has been raining quite a lot up here in New Hampshire, and it's been chillier than usual, but they laid like stars all through a cold winter. Am I doing something wrong? Is there something I should be looking for, or is this normal? I really do appreciate any help you might give me. Thanks!
