I think I really screwed the pooch here

[Noah Way Farm]

So, I set a bunch of eggs a couple weeks ago - out of 13 eggs, only 4 are set to hatch. However, even though they are all the same breed, two of the eggs are far more developed, and yet the other two clearly have life, moving chicks in there. To top it off, because I legitimately didn't think any of those eggs were going to hatch due to an incubator malfunction, I added some fresh eggs to the incubator 4 days ago, and they all are developing.
So, lockdown for the first 4 eggs begins tomorrow. There seems to be no way that the 4 eggs are going to hatch close to the same time. And I only have this one incubator, so how do I handle lockdown? Will lack of turning and increased humidity harm the new eggs?
Sometimes, I can be so stupid....

Youre not stupid. It's an experience that you can learn from.

I would personally worry about the new eggs that you just put in. Make sure you're doing everything to ensure those all hatch. The 4 that you have now that are in lockdown, keep them in lockdown.

Are you hand turning?

I have an auto turner so on a situation like this I would put the 4 in lockdown somewhere where they wouldn't be turned. My turner has a spot to lay eggs where they won't get turned. Doing that you would have to make sure you're there when they hatch so they don't get caught in the turner. Place something on the turner that can hold the chicks till they dry then put them in the brooder.

What malfunction happened with the incubator in the first place?

So, I AM hand turning, so there is no turner to worry about. They are ON a turner, but it doesn't actually work. The incubator is a Hovabator still air. What I have been doing is elevating opposing ends 3-4 times/day with a 2x4 underneath the incubator, so it tilts at an angle. I go counter-clockwise with it every 6-8 hours. So, it isn't a matter of the chicks getting caught in the turner, but a matter of the new eggs not getting turned - would it be better to continue turning? I don't know what happens to hatching eggs if they get turned, but I can't imagine a hen takes that much care to not turn them.
I am more concerned about increasing the humidity for 3 or 4 days. How will that affect the new eggs? How low can I reasonably keep the humidity during lockdown and not cause the hatching eggs a problem?

 

[Noah Way Farm]

Oh, and the malfunction was excessive temperature on 2 separate occasions, to about 106 for at least a few hours. This incubator is worth every cent of the $10 I paid for it....

 

[FortCluck]

I would hand turn the new ones and leave 4 other ones alone. Raise the humidity a bit for hatching of those 4 then let the humidity go down once they hatch and continue how you normally would with the other eggs.

I am curious on if you had any hatch?
