Was the cloaca round or square? That might have something to do with it! An egg is incredible strong due to its shape and can sustain incredible compression pressures and will fall out the cloaca very easily due to its shape. That is all you really need to know. Would you rather push out nice angular blocks that are structurally weak or a nice round ovoid that contains your heritage.
