A chicken adopted by schoolchildren stunned the class by producing giant eggs nearly twice the normal size. Little Lil, being cared for by pupils the Raikes Centre, in Kingsholm, Gloucester, lays eggs measuring 4.3in (11cm) rather than the usual 2.4in (6cm). Teacher Kate Farminer said pupils were astonished when the Columbian blacktail cross began producing "supersized" eggs weighing 7oz (200 grams). The average egg is around 2oz (60 grams). Source: BBC
