Farming

A farmer went to a local bar and ordered a glass of champagne.  
The woman sitting next to him said, 'How about that? I just ordered champagne too!'
'What a coincidence' the farmer said. 'This is a special day for me. I'm celebrating.'
This is a special day for me too, I am also celebrating,' said the woman.'  
'What a coincidence!' said the farmer. As they clinked glasses he added: 'What are you celebrating?'
'My husband and I have been trying to have a child and today my gynecologist told me that I am pregnant!'
'What a coincidence!' said the man. 'I'm a chicken farmer and all last year my hens were infertile, but today they are all laying eggs again.'
'That's great!' said the woman, 'How did your chickens become fertile?'  
'I used a different cock,' he replied.
The woman smiled, clinked his glass and said 'what a coincidence!'
