Culling is a valid management option vs treating illnesses. Some flock keepers here cull at the first sign of an individual becoming sick, and they have never needed to deal with treatments. They also don't know what diseases their flocks might be carrying since they don't usually bother with necropsies, either.
This isn't to fault this practice. It's a legitimate method of dealing with possible illness in a flock. Being emotionally attached to your chickens precludes this management practice, though.
