I've noticed a behavior with my laying hens that I'm curious to know if anyone else sees it. When one of my girls is in the nest laying her egg, another one will stand in front of her on the ledge. The hen on the ledge is always facing out, and will usually only get down when the other one is finished laying. So you think she's guarding her "sister", or just waiting her turn? Whatever it may be, it's cute as heck to watch.
