I'm on day 29 for duck incubation. 10 viable eggs total, 7 of them hatched 2-3 days early and are doing fine. The remaining 3 are now on day 29, are still showing signs of life but have not broken thru to the air cells, which are quite small. I had a weird temp/humidity fluctuation ( temp dropped a few degrees, humidity spiked to around 80%) around the time that the 1st seven were moved from incubator to hatcher. I have regained the temp and humidity levels, so I guess my question is..now what?? Should I wait this out or intervene is some way? Thank you for your help.
Nothing unusual for ducks to go past 28 days. Many will be 30 - 31. My longest to date is 34 days to hatch.
