We started out with banty hens and added a Rhodie rooster a year ago. They all get along great, and the ladies really enjoy having a man around. We've allowed our hens to set a couple of times since then, and the offspring have turned out banty-size or a little bigger.
Like folks have said previously, if you collect the eggs every day, you won't end up with chicks, and fertilized eggs are perfectly edible. Our problem sometimes is when we have a broody hen, and she sits on an egg for a couple of days before we collect it. Since the blood vessels are the first thing to develop inside the egg, it might be bloody inside or the yolk will break immediately. So, we always break our eggs into a separate bowl to check them before we use them. When none of our hens are broody, we don't have to worry about it.
Good luck!
