I have a mature flock (1 1/2 year old) of Buff Orpingtons who lay everyday in their nests. Every month or so however I find an egg below their roosting bars on the coop floor. This is happening at night as I don't see the egg when I put them up for the evening. I know that in the scope of chicken problems this would rate pretty low, but I am curious. What I want to know is, "do chickens have "egg dreams?" Has anyone else had this problem?
