No, not really. But I could see why he would think that if, for example, he had been exposed to a flock with a lot of broody hens in it. I personally have a lot of broody hens and it does seem like they are constantly broody. Unless I desperately want to hatch some eggs.... At that point I'm pretty much out of luck!
I also have hens who aren't broody. Never have been, never will be. I could keep them in a cage with eggs forever and a day, and they would not sit on them. I'm with you, that would be cruel.
Now, back to the broody hens. When I see that one of my broodies is starting to get in the mood, sitting on the nest day and night, puffing up and screeching at me, puck-puck-pucking around when they do come out to eat and drink, well, I do put them in a little broody house with eggs(golf balls), food and water. When they get used to it and accept it as their nest, I give them fertile eggs. And it is so easy from that point on. They take care of everything. But you have to have a hen who is naturally broody, and she has to be having a hormone flare up, or it just won't work. A lot of today's hens have had the broodiness bred out of them. A broody hen is a relatively unproductive hen, from an egglaying standpoint. So most hens that are bred for production won't be broody.
