These people are adults
Sorry to rip that scab off your alcoholism but neither eggshells nor eggs contain alcohol, and these people are drunk.
Alcoholics are often desperate to cloak or conceal their alcoholism.

“An eggshell parent is a parent who struggles with regulating their own emotions, and as a result, their children feel as though that they need to walk on eggshells around them due to fear of that parent maybe having an explosive episode, or shaming them in some way or expecting them to do something that’s outside of the range of what’s developmentally normal or developmentally expected,” said Natalie Moore, a licensed marriage and family therapist in California.
I'm not really certain about A.A., and I am not affiliated or associated with them. So after you have cracked the said eggshell and fried the egg, or perhaps boiled it and then cracked the shell, and eaten the said egg with a good healthy breakfast, you have probably realized by that time you don't really have an "eggshell" problem at all.
An eggshell parent is not a clinical term, but is instead a way to describe a host of personalities and behaviors displayed by these kinds of adults, according to experts.
So stop charging professional clinical fees for it if it's not a legitimate clinical term. I'm sick and tired of pop psychology.
The adult children are obviously drinking themselves if they are complaining about the behavior of their drunk parents without admitting alcohol has anything to do with it.
Talk is cheap. Groups like this exist mostly on a donation basis, and I am sure they are willing and able to talk quite competently about such issues without charging professional fees or filing civil commitment proceedings in court.
