Had chickens a few times and aside from one smart hen that made it 4 years, they all got killed by hawks. Had three roosters in one batch. All have made it to full size and then got picked off one at a time. Better when I had dogs here but I’m not feeding dogs to get eggs. Might do a chicken tractor so they have fresh forage all the time.
Friends had a roof on their chicken yard of chicken wire. No trouble with hawks.
We had a very good natured old dog “adopt us” and that was great (for protecting the chickens) but, yeah, it’s not economical unless you have a lot of chickens. What seemed to help most here was ending up with large roosters with white capes and dark bodies & wings. Apparently the hawks think the roos are bald eagles?
