Interpretation 2 — Gustavus Hindman Miller

To see a fowl with her brood, denotes that, if you are a woman, your cares will be varied and irksome. Many children will be in your care, and some of them will prove wayward and unruly. Brood, to others, denotes accumulation of wealth.

Interpretation 3 — Katherine Taylor Craig

For a mother to dream of seeing a brood of chickens under a hen warns her that despite her care some of her offspring will stray (Artemidorus). Obviously this dream is traceable to maternal anxiety.
