I am stumped! Penguin hatched out of a mystery egg from My Pet Chicken. The egg was blue-green and Penguin hatched looking like, well a Penguin, hence the name. He/She (?) was HUGE when compared to the other hatch mates, all Isabelle Orpingtons. So thoughts on breed and gender? I am leaning toward roo but have no clue on the breed! Penguin is 16 weeks.
