What's the price of chicken yellow?

No "yolk" does not mean it does not exist. Some say that the yolk has changed, while others say that it is chicken stones. I have one at home. I dare say that the yolk is definitely not changed, because I found that it is layered and has a faint fragrance. When I add it with my tongue, it has a faint bitterness and sweetness. It feels lighter than an egg and its surface is yellow. Covered with a film, it is unique.
