A Chinese farmer has given his chickens specially made glasses to stop them fighting.Zhang Xiaolong says his aggressive roosters have become much more peaceful since he gave them the plastic glasses.The glasses are actually blinkers which prevent the birds seeing straight ahead - making direct confrontation more difficult.Instead they have to look around the sides which makes them more cautious.Xiaolong, of Xiamen, southern China's Fujian Province, said: "My roosters were always fighting each other - I was losing ten birds a day."I was inspired by my own glasses and thought if I could just block their view so they can't see each other directly, they wouldn't have fights."It has worked really well. They can't attack each other so confrontations have been minimised."Source: orange.com
