We've bred hundreds of Narragansetts, primarily for conservation purposes, and never had an even mildly grumpy one. The stags always place themselves between strangers and their wives in the breeding season and then display continually, sweeping their primary feathers across the floor as well as booming and gobbling. I guess if someone was unfamiliar with livestock and didn't read the defensive signs they could push the stag's tolerance level too far. The Narragansett stags reach 14kg when mature so, no, I wouldn't want one flying at me.
