It really is amazing how quickly the roosters know when a hawk is nearby.
It also helps to not have any places for a hawk to roost. They like to sit and study their prey for a time before swooping down for the kill. So trees and power poles are perfect places for them to sit and think.
We lose a few chickens to hawks each year but thankfully it hasn't been a serious problem. I'm not sure what
@Trish is talking about with a topper...
