No egg during Turtle breeding

I'm currently playing the beta on Xbox one, I've been trying for about 2 days to breed turtles. I've explored and found numerous turtles in the wild. After feeding the turtles, the experience orb is generated but no egg is ever laid. I've spent up to 30 minutes and some locations keeping the turtles in the area in which they were generated. However no egg has been laid once.
