View. comments. Big Bird the hen is laying claim to a new world record this Easter after her owner Harry Evans spotted this incredible mini egg in her nest. Barely bigger than a 5p coin, it measures just 0.9 inches (2.5cm) long, has a diameter of 0.79 inches (2cm) through its widest part and weighs 0.26oz (7.3g).
