Ajuong, Maker and Dhieu, pose for a photograph with their mud cows, in Mingkaman IDP camp. The fact that their families’ real cows are far away in cattle camps being looked after by their elder brothers doesn't stop Ajuong, Maker and Dhieu from creating their own herds to look after. Fashioned from clay-mud and water from the Nile, the boys, aged eight, seven and five, spend the mornings making a new herd, and then the afternoon concocting adventures that they all share. 'One day, we'll be in the cattle camps being responsible for the cows, it's good we practice now,' says Ajuong, who magnanimously says he and his friends are 'as good as each other' modelling the clay cows. It is clear, however, that long horns are favoured. Some of the South Sudanese cows seen wandering the village of Mingkaman, where the boys live alongside more than 100,000 others who fled recent fighting, do have truly astonishingly long horns. Why are they better? 'I don't know, they are more interesting to look at and play with,' Maker says. 'They are worth more at market for dowry, too.'
