My main predator problem seems to be from the random Hawk attack. I have what I would consider a number of crows/ravens in the area but what can I do to encourage them to hang out at my house? I have bird feeders in my front yard but I never see crows on them. The chickens aren't too brave and typically keep to the backyard....of course its more open in the back. They have places to hide but I always seem to loose a young pullet. The other issue is the random stray dog that hasn't gotten the 12g message yet.
