I bought 4 buff orp hens March 5. On April 4,5,and 9 I got 1 egg each of those days. Nothing since. Nothing has changed. All the hens should have turned 1 this month. All healthy,3 squatting.The roo is even mating them. There is no where to hide eggs and no signs of any being eaten. Their coop is in a kennel next to another coop in a kennel.any predator could take eggs from their neighbor so don't think it's that. What gives?
