Minecraft wiki entry for Turtle, associated text: Turtle eggs can be placed on any block in clusters of up to 4, however, they hatch only on sand or red sand, above or below water. Eggs can be broken without tools and can also be trampled by living entities falling or walking on them. When a multi-egg block is trampled, eggs are broken one at a time. A turtle can walk on the eggs without breaking them. Harvesting eggs with Silk Touch drops an egg, which the player can collect. Mining an egg with Silk Touch resets the egg's growth.
