It was Mary's birthday.Her uncle wrote a letter and told her he would like to send her some chickens.She was very happy because she liked eggs and chicken."I can keep the chickens for their eggs or eat them,"she thought. When the chickens arrived the next day, they were all in a box.Mary took the box off the truck and began to carry it into her garden,but the box of chickens was so heavy that she dropped it.The chickens all ran out.They ran here and there.Mary spent hours in trying to find them. A few hours later her uncle came.He asked."Did the chickens arrive safely?" "Yes,but I dropped the box.The chickens ran everywhere.It took me the whole morning to look for them,"Mary said. "Did you find them all?" asked her uncle."I hope so,"Mary answered,"But l only caught eleven of them" "That's very interesting.I only sent you six."her uncle laughed. It took Mary   _   to find the chickens.
