When is the Earliest I can Stop Turning

[aegg]

I have five duck eggs in the incubator and I've been turning every day three times a day. Anyways, I'm leaving town for a little less than a week on day 19 and was wondering if I'll need someone to turn the eggs for me, or if they are developed enough not to be turned at this point?

The earliest I've ever stopped was day 24. :/
