My hen Edna has been sitting on a nest of a dozen or so brown eggs for at least thirteen days (at most maybe sixteen, I was house-sitting for someone when she started) and I've really been struggling when it comes to candling. Today I decided to try again (much to Edna's dismay) and saw several different things. I saw large black dots in some of the eggs and even larger dark masses in others. What the heck am I looking at? Is she further along sitting wise than I thought she originally was? I didn't see too much movement but I didn't see anything like the red circle either. I don't know, attached are some drawings I did to show what I was seeing since it's so hard to take pictures of dark eggs. Black=masses Also she has been collecting eggs over the past week from my other hen who has been laying so could I be looking at a bunch of different hatching dates?
