Weird screech after dropping something

[chickenman786]

Hi i noticed my hens screech after the wind knocked some plastic trays on the floor, creating a load noise. The screech they did was hi pitched and lasted for about 1-2 seconds, simmilar sound to an eagle.

This is the first time ive ever heard them make this noise. Could it be a sound they make when they are shocked?

They make all kinds of noises...most often we have no idea why they made what noise.
