All that clucking in the Oregon State Senate Tuesday was on a serious issue: the living conditions of egg laying hens in Oregon. Doctor Paul Shapiro of the Humane Society says keeping hens in typically small cages is unhealthy, often for humans.  He says caged operations for laying hens have higher rates of salmonella and other problems, than do cage-free operations. Oregon lawmakers are considering a bill to enlarge hen cages. But the law would not take effect until 2026. More public testimony is scheduled.
