I dreamed that the pork I bought turned into a rooster.

This can't be found in Duke Zhou, but the principle should be equal to the dream that the dead become living or come back from the dead. If it is such a dream, the answer is as follows:

Dreaming of coming back from the dead means that a good body may need to be maintained, but if you dream of your competitors coming back from the dead, you will beat them and make yourself stronger than before. But considering that your dream is to turn pork into chicken, it is better to be a "servant", because food and you are the relationship between service and being served. Therefore, dreaming of a servant coming back from the dead shows that your interior is being disintegrated by the enemy, or that husband and wife need to strengthen communication to prevent the marriage from deteriorating, but they can't take tough measures.
