I got a batch of ee pullets last august. Vaccinated all seem healthy but one Valerie is smaller by far. Appears to be blind in one eye. Wobbly on her feet bottom of pecking order and a true sweetheart. However never laid an egg. Infact her pelvic bone hasn't speard at all any ideas. No signs of sick. Whole flock has been dewormer and treated for coccidosis. Can't eat her as she is small and my daughters hen. Any recommendations. Want her to be happy but the wobbly legs worry me
