I'm on day 16 of 17 but I had forgot to turn the eggs from day 11 I just remembered now crap. Will that effect my hatch?? Please?Your babies could still be ok. It also depends on how far along they are in their development. Hopefully, they're ok. Even the ones you think are duds, I'd still hang onto them for a few more days. How many days are you into incubation?
Good luck to you and your chookies.
