So I have done nothing different than with any other hatch, but for some reason this hatch is messed up. So I set seramas on the 12 th (night) and mottled Cochins 24 hours later. Yesterday was day 22 for the seramas and that's when they all hatched. Usually they hatch on day 19. Today is day 22 for my cochins so I'm hoping they will hatch but so far not even a pip. I candled and every egg on lockdown was alive. Humidity was good and so is temp. What's going on?
