Ok, got home and as I worried I lost the shrink wrapped egg I oiled, the oil dried on, Husband didn’t re oil it, he was worried to open the incubator. And the poor thing was basically shellacked in place. Of my 7 remaining Marans eggs, from my probably too young but I tried anyway pullet, two are good, chirping and alive. One is shrink wrapped much like the last chick... not internally pipped yet... but with a dried out inner membrane. It’s my fault, I know. I have oiled it... it’s still very much alive, humidity and temp returning to 70% and good... how often will I need to re oil this chick? Is there anything else I should do?
You can see it’s still alive but I can’t see the beak at all... it looks much like the first one did. I’m almost done here, down to my last three eggs, the others all quit, not especially early but not particularly late. Considering how young mama is I’m not as surprised by this.
I'm so sorry!

I never used the oil myself, I've only used water just to check for veining so I'm unsure of how often to apply it.
