A lot depends on when it was unplugged. Chicken eggs don't really need to be turned after two weeks. The first week is most important but there are some benefits for turning that second week. If it was unplugged fairly recently I'd expect a normal hatch.
Two main benefits of early turning is that it helps the body parts to form in the right places and it keeps the yolk and developing embryo from touching the inside of that egg shell and sticking. What could, might possibly, maybe happen is that you get a bad hatch rate or some malformed chicks. No need to lie to you, turning is important. But stuff like this happens a lot. Quite often it's just not a big deal, usually not as bad as it could be and not as bad as we expect. Certainly do not give up hope.
Good luck! Let us know how it goes.
