A rooster has appeared suddenly at my house and in my front yard
gardens. This bird crows loudly all day and early in morning.

The rooster perches on my front porch wooden rails and makes droppings
[fertilizes] porch cement. With Bird Flu concerns, we do not need a
ROOSTER making droppings and living on my property.

Try as I may, I cannot discourage that Rooster from sitting on my front
porch. What can I use to make the smell of my front porch obnoxious to
this old Rooster?

Really need help. Dave_S
