I have a silkie hen who is under a year old and has only laid 3 eggs. Today i noticed that she had watery stool and had gotton some on her. when i was trying to clean her up a bit i noticed that her vent was pulsating, so i checked to see if she had laid which she had and her egg had stool all over it. Well, its been about 3 hours and her vent is still pulsating. Anybody have any idea what is causing this?
