Please explain, I don´t understand your question
Edit: I found an explanation
"You use the expression when you are really surprised about something. If you want to say: That can't be true!
The stork used to be a harbinger of good luck for many people. According to legend, the stork picked up newborn babies from the source of life and brought them to their parents.
In addition, there were already dietary regulations in the Old Testament, in the Book of Leviticus, that stated that certain animals should not be eaten. We know this about pigs, but it also says, for example, that you shouldn't eat swans, eagles or storks. This is linked to the idea that one should of course not fry an animal as noble and lucky as the stork.
So the answer is:
The expression “Fry me a stork” is used when something really unbelievable has happened. The expression is explained like this: The stork used to be considered a good luck charm, and it was also on the list of animals that, according to the Old Testament, should not be eaten. So it was something unthinkable to roast or eat a stork."
