Call of Juarez: Bound in Blood

In many chapters, you'll come across some chickens. Just throw a dynamite at them until you reach the 10 heads count.

Here's a quick one, if you're in a hurry. In chapter IV, after leaving the saloon, getting rid of the guys outside and watching the cinematic where the bad guy takes the girl away, you'll come across some other enemies to take down. Here, there are 5-6 chickens walking around. Just take them out with the dynamite, then reload your checkpoint and do it again once to get the achievement.

Chapter IV
Just after leaving the saloon and watching the cut scene for the kind fellow who took the woman away from Ray and Thomas, Follow him around that corner to an immediate area of conflict. Here you can get two achievements, Arkansas Fried Rooster and Fireworks.
First off should be Fireworks.
Clearing enemies that will only cause you trouble would be a good first step. I usually hide where the dynamite can't hit you and you can still shoot the spurs off the guys trying to kill you. Now, to stand by a pillar or fountain that is in front of the building that is in the immediate area after you turn the corner from chasing the kind fella. From there you have cover so the dynamite can possibly bounce off and roll away causing less damage. And now it's up to you to find the spot to aim at where you see the dynamite coming from over top the building that you are positioned in front of.

Arkansas Fried Rooster, after clearing the enemies and the dynamite throwers, you're left to do battle with chickens. They don't put up much of a fight with a stick of dynamite. Kind of sad, but blowing them up will get you closer to your achievement. Just reload your checkpoint to rinse and repeat till you've got your achievement.

Happy gaming.
