Hey Fallen,
not a dumb question. Most people want to get different breeds and it is sometimes easier to get a dozen eggs then it is to find a hatchery or breeder to get chicks from. Some chickens are great for broodiness and other breeds are not, so if you want the breeds that are not very broody but dont want the work of an bator you need s good broody. In my experience silkies are the best broodies and I also have some banty mutts that are always broody. But then I also have americanas that I love the colored eggs but they wont sit for a million mealy worms..lol I had one americana hen go broody for about a week and then she had had enough. It is all what you want, it is also cheaper to get eggs then chicks on average unless you are within driving distance of a hatchery so you dont have to pay shipping or have the minimums that they need for shipping. Also you just have times where a hen will not break a broodiness and you want something new. Also if you want ducks, turkeys, guineas, or who knows what else put it under a broody and she will try to hatch it. I think a goose eggs is about the only thing I wouldnt put under a broody since it is SOOOO large. If you did you could only put 1 and she might loose interest. Also depending on your area it is great to let the hen keep the chicks. I personally dont have a place that they can be totally safe and find it easier to pull the chicks after the mother hatches them out. Also the hen will usually go back to laying a couple weeks later unlike if you leave chicks with her she will not start laying until they are ready to be on thier own. It is truely what works best for you. Jenn
