I guess we have just been lucky! I have only seen a few hawks, but the crows seem to run them off?!?! I have a neighbor's dog that killed one hen and tormented two more and my roo... but he's been gone form several months now. I did have a mystery attack about one month ago. I had a buff pullet ,that I JUST let out for a few minutes, have a section of her head scalped! But no bears or other things! I know some of ya'll are not too far from me, guess my dogs keep things scared off...
