Since only the eggs of one chicken are being eaten, perhaps that chicken is lying thin eggs that are breaking in the nest box. Even chickens that aren't normally egg eaters will quickly eat a broken egg. Try adding some extra bedding to the favorite egg lying spot and set out a dish of oyster shells near their water so they can boost their calcium if they need. I hope it's a simple fix for you and doesn't become a serious problem.
