Found my young Roo dead with feathers plucked all around and a big hawk took off from the tree above. And missing a young sex-link hen too. I hadn't had any deaths in so long because our three big dogs chase the hawks away but they were inside. I am nervous now that the hawk will be back. I suposse I could get an older roo? Is that ok that I introduce a new Roo into the flock? Mine was only about 5 months but he was a big guy already bigger than my full grown hens, but very sweet, a silver laced Wyandotte. Poor guy. I am so heartbroken!
