Minecraft wiki entry for Turtle_farming, associated text: If you see turtles instead of eggs, look around the nearby beaches to see if they've laid eggs. If you don't find eggs, use sea grass to lure two of them onto a beach, feed them sea grass to get them to breed, and then follow them to where they want to lay their eggs. Only one of the two turtles lay eggs. If one looks slightly fatter after mating, follow that one. If you can't tell, try to keep track of both turtles until you see one of them splashing sand. A second player in the same world can help.
