You know, even if your turner hasn't been working right from the start, if that's the only thing that goes wrong in the whole incubation you could still get some chicks. I remember reading about an experiment (posted on this forum) where someone didn't turn their eggs at all - not once in the whole incubation - and they still got about a 20% hatch. I also remember reading about someone who accidentally forgot to switch their turner on for the whole incubation and ended up with about a third of their eggs hatching. I'd suggest you just keep turning them by hand and wait to see what happens.
