The eggs laid by chickens are very small and have no yolk, because foreign bodies such as exfoliated mucosal tissue, small blood clots (caused by follicular bleeding during ovulation) and worms in the intestine (sometimes migrating upward to the fallopian tube) fall into the fallopian tube, which stimulates the fallopian tube to secrete protein and eggshells and wrap them around the foreign bodies, thus forming a yolk-free, yellow-free egg. This is not a disease, just an accidental coincidence.

This kind of egg is usually very small. Only the size of pigeon eggs and sparrow eggs, about110 of ordinary eggs.

So if chickens don't always lay eggs like this, don't worry at all. Such eggs can also be eaten, but they must be cooked like ordinary eggs.
