I did the killing and scalding though someone helped scald a couple birds. My husband manned the plucker. I did the eviscerating with the help of another BYC member who came over because she wanted to learn how to do it. We weren't trying to move super fast and didn't have more than one killing cone to use at a time. All done, it probably took a couple hours for only eight birds. If were were really trying to move through them quickly and had more than one cone set up, I'm sure it would have been far less time.
