Will a large dog keep away hawks? My chickens love to be let out of their run so they can peck around the back yard. I only let them out if I am out there. This morning I heard "woosh" over my head and it was a giant hawk, and then I looked up and saw not one, but two giant hawks flying in a circle over our yard. I ran around and picked up my chickens and put them back in the run. Even though only 4 were out... the other 4 had already gone back in the run...I was worried that I would not be quick enough getting them all back in the run before the hawks would get them. We have a Shih Tzu. Definately not a big dog...probably Hawk food too. I was wondering if we had a large dog out in the yard would the hawks stay away. Like a collie.
