Golden Fields - 2

Strategy
First, protect all birds with Red and Matilda's secondary skills when their secondary skills have expired. Then, attack the Worker first, Farmer second, and Foreman last. Repeat this until you win or lose, but be careful! He will also activate Power Up, which can also increase attack power of all Pigs by 30%.

Summary
Farmers are stronger than workers, but you should first focus on the Foreman because he is the main danger of the pack.
