I am not sure who's doing it, though I have my suspicions, but one or more of my flock has taken to breaking and eating their own or other's eggs. We used to get 7-8 eggs a day from our 8 birds; now we only get 3 to 5, and often find a broken shell or two in the nests. I've seen the hens go crazy over the scent of a yolk: they are absolutely crazy to eat eggs. I'm suprised actually that they don't eat ALL the eggs they lay, now that they have the taste. What can I do about this? Has anyone had this problem before?
