Why is a rooster often used in farms to wake people up?

because it makes a loud noise and its voice box has a peculiar muscle that we humans don't have and trhis allows them to make the loud noise that they make.

the reason it is used is that the egyptians used to belive their god was a rooster and that it would guide them through their life and help them perform daily things, but then they belive that their god evolved, so this thing is 0000' of years old!

thanks, mr rooster EXPERT!
