i had 2 turtles spawn at one of my villages.  i created a fence around them on a shore line.i fed them seagrass and they made 1 egg.  that one hatched.  i also planted a few eggs and hatched all of them on one beach.  some don't eat and others eat and mate and get the xp but they will not lay eggs.  i can't grow my turtle farm.  i tried planting more eggs on another beach and hatched them and mad a home for them in both areas just like wattles but turtles will not ley eggs.
