They are two halves. I cut the inside bulb and cable slots, and the inside of the thighs first, and then the outside of the bodies. I make two complete bird bodies from a 500x300x40mm cutting board. The legs are made from the same material, but I find thinner cutting boards for them. The toes have carbon fiber inserts on the underside for increased strength. I cut slots for the carbon fiber first and then glue the strips in place before 3D milling the feet.
They must be wondering why they are selling so many cutting boards in the store in our tiny town.
