Minecraft wiki entry for Turtle_farming, associated text: A turtle farm works while you're away from the keyboard (AFK). Many in-game days are required to hatch enough baby turtles to create a sizable population of turtles laying eggs in your farm, but you can speed things up by actively managing your farm, using sea grass to lure back the turtles who left, feeding sea grass to pairs of turtles, and feeding baby turtles.
