My little flock of 5 hens have been laying steadily since they started in October. (They have light in the coop. ) Suddenly last week we went from 3,4 or occasionally 5 eggs a day to 2, or today, none. A few days ago I found the frozen remains of a broken egg in one of the boxes. This morning there was a lot of poop in one, and tonight at 7pm both were occupied, I assume by girls planning to sleep there. What is going on? What steps can I take to break them of new bad habits? I read the article, six ways to stop egg eating, but I'm not 100% sure that's what's going on.
