Here's my view, for what it's worth. After losing three hens to internal laying and about to lose two more, all same age, all hatchery stock, I am happy for a hen to go broody once or twice a year, just so she can have a two month break from laying. I truly believe natural broodiness prolongs their lives, and I qualify that statement by adding that, as long as she does not starve herself to death or try to kill herself through dehydration, i.e. a normal broody, then she prolongs her life. Broodiness is bred out of even normal broody breeds in favor of high egg production. Yes, you get fewer eggs, but you dont have to watch hen after hen waste away and die earlier than she should from egg material building up in her oviduct, as I have. I'm not saying that not going broody means she will become an internal layer, necessarily, but it sure is hard on the body to lay eggs day after day with no real breaks. My hens who died from internal laying didn't even take a long break to molt, either, just two weeks each. They were bred that way, I believe, selected for non-stop laying.
I've had three different hens go broody, all were sweet as can be with us, each allowing us to take them off the nest and put them back when we fed them daily. All allowed us to handle the babies, too, so I haven't had a true psycho-broody yet.
