I got 26570 on first play! Seems like it's the highest score from the comments so pretty happy about it. The game is very nice, it's a simple mechanic executed well. I think the addition of the blue troll is a great idea as it forces me to think a bit more about my whacking in order to get more chickens(although I realised they give new chickens mid game only).
My only suggestion is to clean up the blood after some time. The blood is red, and bad trolls are purplish so they blend in with lots of blood, and I didn't see them sometimes.
