After unsuccesfully trying to open the egg carton from the hinged side and cracking the lone egg in there, our carton still only contains one egg. Before you pass too much judgement on me and my coordination: it was one of the clear plastic, tri-fold cartons. So technically both sides are hinged. But, whatever. That is not the point. The point is: over the last 2 or 3 days only one egg has been produced between 2 chickens.
