Im not sure if I've put this in the right place but here is my dilemma. I've had some eggs sitting under my clucky hen and one hatched last night and is happy and healthy. the other egg hatched this arvo while i wasn't home and i came home to find this by the looks of it it hasn't fully formed of somethings gone wrong Im not sure. could anyone help me out what is this /what causes this? and is there anything i can do to prevent this in the future? Many thanks.
