Answer:
Farmville free stuff is not actually away of getting products for your farm, it is to attract more facebook users to use different apps which have very little purpose. Another thing to look out for on facebook (farmville) is the ecards they inform you that you can have all kinds of wacky gifts but this is impossible. The only way to receive gifts on farmville is from your friends on facebook or if you buy or adopt. You can only adopt if a friend finds an animal, this will appear on you home page of facebook.
I hope this helped
