Perform surgery on pigeon eggs

Ma Zhiyuan is a neurologist from Nanjing Chinese Hospital, who has saved thousands of lives during his 20-year career. Today, the doctor performs a complex surgery on pigeon eggs as a simulation of the difficult operations that may be carried out in the future, although surgery is a simulation of reality, but it is more difficult than real surgery. The doctor must make sure that the eggs do not harm the thin inner membrane of the egg. He takes a piece of hen's egg and then sews it on the hole of the pigeon's egg membrane, and turns the pigeon's eggs. Will the eggs be removed from the sewed membrane? Does your doctor succeed in this special surgery?
