I'm apologize for getting here so late. Thank you for referencing me @Vampstorso
@its raining hen How close are the eggs? Do you have an incubator?
I've dealt with cold duck and eggs, but I'm afraid I haven't got any experience with badly damaged eggs. If they were mine, I'd try this if you have an incubator. If I have an egg where the air cell is growing to fast or, if I have an egg zipped and making no progress/or if I've checked on a chick and I'm concerned the chick will dry out...I've put the egg in a small container with a damp paper towel hung over the top edge of the container and I place a sandwich baggie over the container to hold the humidity in.
Here's a chick that I had used this technique after it's hatched. You can see the dry paper towel hanging over the side. You'd have the paper towel damp and set a baggie sitting loose on top.

Please check out the above article from
@Pyxis. About 1/3 of the way down under "further assisting" it shows a picture of an egg that's been opened, and has active blood vessels so it's too soon to assist. She mentions using coconut oil. Some use neosporin
WITHOUT the pain killer (very important) to keep the membrane moist. I've purchased neosporin for us (without the pain killer, lidocaine) and to keep on hand use for chicks/chickens.
Hopefully someone else may have good advice. I hope your eggs are still ok.
