Help! Problem with my duck eggs and one has already pipped!

[Suzyq16]

Hi, this is my first time hatching duck eggs ( or any type of egg for that matter). My 9 Rouen duck eggs are on day 25 in the incubator ( Hova-Bator). What should the humidity and temperature be if one of them pipped last night? I can see the crack and a lot of movement and the other 8 are all moving too. I can even hear some chirping. There is a complication though, 3 of the eggs air saks are too large, 3 are too small and the other 3 are in the middle. What should I do about the humidity? I’ll post pictures from yesterday morning (day 24.) I haven’t opened the incubator since I saw one pipping today. Please let me know what eggs I should be worried about and if there is anything I can do to help them. I’m a nervous wreck! I already feel like their mother and I’m so afraid I’ve done something wrong! Any and all advice is welcome! Thank you

I like to keep the humidity around 60-70% at lockdown, but there isn't a real set humidity to go off by that's why it's important to track the air cell or weigh the eggs throughout incubation. All your air cells look good, the ones that look big are just doing the "dip down "which means they have a good three/four more days to go before they hatch. The eggs with a smaller air cell should start doing the dip down soon enough. Were these eggs started on different dates?

They were all started on the same day, March 24th. 2 more have pipped since this morning. Pipping is when they start trying to hatch right? I see small cracks on 3 eggs of them and a lot of movement. So the “dip down” means they should hatch in 3 or 4 days. The ones that haven’t dipped down yet should hatch after the ones that already have?
What temperature should I have it on since they are pipping? 98.5 or 99.5? Do I need to lock it down now?

Yes, they externally pipped and will probably be out of the shell in 48 hours, they are very slow hatchers so don't be concerned of they take longer than that. In my experience Yes, after the dip down, shadows of the ducklings start to appear, and then after that they internally pip and then externally and then they start to zip.

If you are using a Forced-Air the temp should be at 99.5F, Yes, you are in lockdown.

One of my eggs has a mark on it. What do you think it is?

Does forced air mean if I’m using an incubator? I’m using a Hova-Bator. What does zip mean?

No, If it has a fan to circulate the air around the Bator. When the ducklings start pipping through the shell in a circular motion to get out of the shell. Like this-

Thank you so much for explaining everything to me! I really appreciate it!

5 eggs hatched this morning and three more are about to. The humidity is 85 and the glass is foggy. Is that ok? I’m having a hard time maintaining the temperature at 99.5. It keeps dropping Between 95 and 97. What should I do?
