"Jacob asked the shepherds, 'My brothers, where are you from?' 'We're from Haran, ' they replied. He said to them, 'Do you know Laban, Nahor's grandson?' 'Yes, we know him,' they answered. Then Jacob asked them, 'Is he well?' 'Yes, he is,' they said, 'and here comes his daughter Rachel with the sheep.'" NIV translation
We see that Jacob did not even know where he was until he asked the shepherds and they informed him that he was at the right place. We are also introduced to Rachel and we see that she was a shepherdess as she was bringing her father's flocks to be watered.
It was common practice for a woman to tend the flocks if there were no male children in the family. As the youngest child, she would have been the one that was stuck with the job of tending the sheep. I say stuck because sheep smell and she would have been with them all day and cared for them.
She would have had to be strong to protect them from predators and also patient to deal with their constant desire to wander off.
