I’m not sure which bit you’re referring to, but I think everyone keeps chickens for different reasons and has personal opinion of what level of intervention they have with their birds.
Personally, mine are pets. I only have a handful (7 in total including the chicks) and the broody was hand raised from a chick herself last year. Hand feeding her on the nest is definitely not natural, and not for everyone, but my birds have been used to that kind of thing. For example... they all have daily cuddles... even the cockerel!

And I know that’s not for everyone!
