My grandparents had a small farm, that they grew crops and vegetables. They also raised dozen of hens and cocks, which were kept, in an area surrounded by a fence for protect. However, there were always several chickens escaped through the fence, wandering freely in the fields.
Last spring, I visited to my grandparents' farm and play near the wheat field. Suddenly I caught amazing sight: a hen was walking past, following by five chicks! No one knew where and when the hen hatched his little kids. My grandma was happy and hurried prepared a new home for the mother and the children.
