I put down dogs because the deaths from dogs could 99.9% of the time be prevented by the dog owner controlling their animal. the rest of the preds on your list are mostly hungry wild animals that are only doing what nature tells them to do.
Raccoons seem to be the most brutal in how they kill. They have a good enough grip to reach through wire and grab chickens and start eating without actually killing the chickens first.
I'm thinking this is a good reason to not use wire-bottom cages without a floored area and/or plenty of perches that are high enough but still easy-for-chicks/chickens to reach for a safety retreat during an attack (Even with small wire mesh, the raccoons could likely munch toes). Also to not use narrow cages, at least without a good, solid hutch/house area, and maybe not even then unless mesh is small (1/2" x 1/2" hardware wire).
Sorry to be graphic, but gotta be careful and protect our guys!
