They don’t injure themselves from falling. If one falls from the roost, its because its already sick.
I’d bet that chicken is diseased, not injured. Probably better to let nature take its course. You don’t want a weak chicken reproducing anyhow where the chickens are having to fend for themselves in feral conditions. Its survival of the fittest, and helping the less fit to survive can be detrimental to the flock. Sometimes what’s best for the group isn’t what’s best for the individual.
