too small to take a chicken away, yes. BUT on a couple of occasions while I was not home I had small hawks kill a chicken and eat it right on the spot.There are hawks all over the place here and a red tailed nest 200 yards from here. hawks are not a problem to me with adult birds. The most aggressive hawk I have here is a Coopers hawk and he is too small to take a grown chicken. Predators hunt based on experience, opportunity or lack of natural food sources. If these birds get hungry, they will try to take whatever they can. I have had great horned owls take full grown chickens, but not very often. They will take a cat too, so nothing is safe if they are hungry.
Bottom line is that it depends where you are and what kind of hawks you have in the area and what they are accustomed to hunting. Some people have a huge problem with hawks..I don't.

This year the hawks have been keeping their distance. 2 raven couples are in the yard often. I think that may be why
