Why do my sunflowers have multiple heads?
Since they come from the same package (your one headed and your multiple headed plant), it could be that your multi head is a hybrid with another variety that has multiple heads. Accidental hybrid if you bought seeds from a professional breeder, maybe cross pollinated by another variety that was growing near by.
Are there male and female sunflowers?
The flowers in the center of the head, called disk flowers, are smaller and quite different in shape from the ray flowers. They are "perfect" flowers, meaning that they have both male and female producing parts.

Can a plant grow from bird poop?
In short, bird droppings make great fertilizer. Many gardeners depend on bird droppings for plants in the form of rotted chicken manure, which increases the nutrient level and water-holding capacity of soil.
Does bird poop spread seeds?
Dispersal Through Droppings
Birds ingest the flavorful pulp; the seeds inside the pulp then move through the birds' digestive systems and are passed out along with their droppings. The fecal material gives seeds a small dose of fertilizer as they germinate and begin to grow.
