Luckily I was nearby when I heard my EE screaming, I ran outside just in time to stop either a big female cooper's hawk, or a male goshawk from a chicken dinner. The other chickens were all hiding on the other side of the yard. She probably finished laying an egg and squawked to find the others... and helping the hawk find her. I got all the chickens to go into the covered run, but the hawk is still nearby, I can hear him/her. GAH! I guess this mean's they'll have to stay where its covered for a while, huh?
