igotgoosed... day 25 is typically the day that duck babies will begin internally pipping. Since a lot of people are not confident with candling and verifying internal pip, it is easier to just lockdown on that date. Goose eggs take 30-31 days to hatch and internal pipping occurs closer to day 28. So, if you are unsure about verifying internal pip, lock down on that date. But don't lock goose eggs down on day 25.
Ok, so to be on the safe side since I haven't seen internal pipping before, I should just lock down on day 28? Is that when I raise the humidity too?
