Just did this as well. My eggs "hatched" but no turtles emerged.
Yet, this is unintended because the gray side of the logs are gray on the map.
I cranked my random tick speed up to 10000 in a single player world and they did fine hatching in 1.12.2 chunks. I wonder what happened because they definitely disappeared on my server before.
