One of my EEs just laid this egg in the middle of my backyard (7pm, almost dusk). She was lurching, like a dog, and laid this egg in the grass. I read other posts where pullets laid eggs like this, but this hen is over 2 years old. She is also lowest in the pecking order. Her eggs are normally blue and recently we had a blue egg that had a heavy swirl on the large end. Is this normal or should I be concerned something more serious is wrong with her? The shell is firm, but it broke when I gently pushed on it.
