Dreaming of a nestling indicates that you may be facing some lack or poverty in your life. It reflects feelings of separation from family members or a sense of distance from relatives. If you are currently going through such a situation, this dream is a reflection of your mental state. It serves as a warning that some changes may be needed in your relationships.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Nestling" (page 302) â resolved via the equivalent "Baby crow" entry.
A fledgling crow in a dream represents poverty, need, separation from one's parents and segregation from one's relatives or clan. If one is experiencing such adverse conditions in wakefulness, then seeing a fledgling crow in a dream means satisfaction of one's needs and reunion with his family. When the egg hatches and the baby crow comes out of it, the parents shy away from their fledgling and remain distant from the nest. Then God Almighty will provide the nestling crow with various types of flies to eat from. Once the baby crow's feathers grow, the parents will return to their nest and care for their baby until it commences to fly.
