A carolina wren had 5 eggs, something happened to her along the way though. And the eggs, there is one that is a little bigger then the other 4 but I know it belongs in the nest because of it's spots. But put up to the light, I can see threw the shell. The egg is half full of something, just half, not all the way full. I would like to know what that is and if im waisting my time. I don't mind but I don't want a heart break.
