Turtle egg doesn't plant

Maybe because they don't have any space. This might very well be a feature rather than a bug.

Have you waited for at least a few minutes? Otherwise there is not enough space for the turtle to lay an egg.

I have waited and they still didn't plant. There was space.

You should get rid of the fences. Turtles need a lot of space, and even then it can take minutes before the turtle's digging animation stops.

Loek I fixed it. They didn't have space. This problem is now resolved
