Excuse me, bird shit fell on your head today. Is there any omen on your hat? Is it fierce? thank you

This matter cannot be judged as good or bad. Bird droppings falling on you are often called "windfall", which indicates that you will make a lot of money, because bird droppings belong to fertilizer and are very nutritious. There is also a saying that bird droppings indicate that you will have bad luck in the near future, and it is very likely that someone around you will get sick.
