Arkansas Fried RoosterG 10

This is an easy achievement to unlock. You need to simply kill 10 chicken with dynamite. It is a cumulative achievement and doesn't have to be done in one explosion. In chapter IV after you leave the saloon and clear out the enemies after the cut scene there is a group of 5-6 chickens walking around. You can blow them up with the dynamite and reload the checkpoint to do it again for the achievement.
