"Shrink wrap" vs. "Sticky chick"?

[GraceHomestead]

Ok I had 5 chicks hatch this morning.
Can you tell me why one of the eggs looks different then the others on the inside?
Was it starting to shrinkwrap or something else?
Normal egg

Different egg

Is this a sticky duckling? It piped about 48 hours ago and this is its progress. Most others are out of their shells already.

So glad I happened upon these articles. I have traversed solo through all of these problems myself without ever having a name for them or even knowing someone else out there could give some hope! I assume everyone else reading these posts, like me, feels the loss of a chick, I go so far as to take every one of them personally. Good to have this page now bookmarked as well as the article I followed from to get here!

Shrinkwrapped chicks were way too common in my earlier hatches. Now I do not open the Incubator until it looks like all eggs are done hatching. Last hatch there were 4 still hatching but they were under all the chicks running around. All 4 shrink wrapped. 3 out of 4 survived because I hand hatched them, zippered their egg for them pulled off the cap loosened them up and put the cap back on. For some reason if I make them break out on their own they survive. When I used to completely pull them out they did not survive.

(ETA: As I understood it...) If you open the incubator during lockdown, the humidity drops and a pipped chick can become "shrink wrapped." They cannot turn to complete the zip.
If your humidity is too high during lockdown, the chicks can become "sticky" and cannot turn to complete the zip.

Looking at a chick, how do you know if it is/was sticky or shrink-wrapped? Is there any practical difference in how these are handled? I'd like to be able to better trouble-shoot on my next hatch by better understanding the difference.

Thank you for your help!

THREAD SUMMARY:
Here's brief summary of what we've discussed. This doesn't represent a 100% consensus but seems to represent the current majority opinion:

Shrink wrapped: before pipping, both inner and out membranes dry tight around the chick; caused by too little humidity throughout incubation

Sticky chick: after pipping, the liquids dry becoming glue-like followed by concrete-like; caused by too little humidity during lockdown

Wet sticky or Swollen: the chick is swollen with water or simply very wet and sticky; caused by too high humidity throughout incubation

Drowning: the whitish outer membrane is dry while the clearish inner membrane is wet, binding the chick; also caused by too high humidity thoughout incubation

*Chicks experiencing more than one of the extreme conditions can exhibit multiple issues.
*These same issues can also occur during natural incubation, under a brooding hen.

This thread was not active for awhile... Do you think my baby could be shrink wrapped? Or why is it stuck in that weird membrane thing?
