Hi there, 
		
		
	
	
		
	 and welcome to BYC!
 
You might need to keep your chickens in a run for some time. Once the hawk learns there is food available to him, he will return. They are very smart and do not forget. I am not able to let my girls out due to the predators in the skies and hiding in the bushes. When I do let them out, I have to supervise them constantly.
 
Great to have you aboard and enjoy BYC!

 and Welcome To BYC!   Sorry about your hen, like everybody else said, it will keep coming back since it knows there are chickens there.  You'll need to either supervise them or keep them under cover for now.  There are a lot of hawk threads in the Predator and Pests forum if you want to see what other people have done to deal with them.
