So, I've been raising 4, what I thought to be, Muscovy ducks. I bought them from a lady who said they were Muscovy, but they started pipping at day 27 and it's day 29 today, so I'm pretty sure they're not Muscovy anymore. We've lost one of the ducklings, and the other one hasn't pipped or anything yet. Anyways, when they started pipping on day 27, they both had only one pip dent mark thing. Yesterday (day 28), duck #1 egg made a second hole in the egg. It's been peeping away and shaking the egg. I've been monitoring them at night, without opening the incubator of course. The humidity is at 85% and the temperature is at 37.0°. When I got out of bed to check on them at 1:00am, there was no progress, still just 2 holes in egg #1, and 1 hole in egg #2. But when I got up at 3:00am, duck #2 had made about 3 holes and was trying to push the egg shell off. I can see a bit of his beak tooe. Anyway, I'm a bit worried about egg #1 because it's been over 40 hours since it started its first pipping. Both eggs are shaking and peeping loudly, but I'm worried about the first egg because it hasn't made much progress. Should I intervene? Should I wait longer? Any help would be much appreciated, thank you!
