A Strung rabbit foot (also known as Rabbit-foot necklace) is made by using a ball of wool with a Rabbit foot, requires level 37 Crafting and gives 4 experience. Rabbit feet can be obtained from the Hunter skill by snaring rabbits. Players must have completed the Eagles' Peak quest to be able to snare rabbits. It may only be worn with a hunting level of 24 or higher.
When worn, it was assumed the player would have a better chance of obtaining a Bird's nest when woodcutting trees. However, Mod Ash confirmed during an Old School Q&A Livestream that the item does not increase the chance of nest drops, only that the dropped nests will have an increased chance of containing bird's eggs.
The eggs can be used on the shrine in the Woodcutting Guild[1] for 100 Prayer experience and a Bird nest with seeds as a reward. There is a 1/300 chance of obtaining a piece of the evil chicken outfit when offering eggs.
