+# Stoneblock 3 Chicken Breeder
+
+## Usage
+
+Set up the turtle like so:
+
+* Any tier mining turtle
+* Breeder on top
+* Chest in front
+* Chest on bottom
+* Seeds in inventory
+* Pair of chickens to 10/10/10 in inventory
+* Run betterbreeder.lua
+
+The turtle will 10/10/10 a stack of chickens
+in the chest below, then stop.
+
+## Compatibility
+
+No clue. Try it on a pack that has the Chickens mod and see if it works.
