Farmers lives and work became even worse when about 20,000 emus arrived. Emus regularly migrate(move from one area to another in big groups) after breeding each year. They return to the coast from inland areas. Western Australian farmers had cleared more land and made water supplies for their livestock and crops better. The emus found that the settlers' farm lands were good places to live. They began to move into farms. Many moved into the farms around Chandler and Walgoolan. The emus ate and ruined the crops. They also made large holes in fences where rabbits could enter and cause more problems.
