I have an opportunity to get 8 three-week-old guinea fowl for almost free. Having never raised guineas, what do I need to know? Housing is my main concern I do have a duck house with extra room -- can I house ducks and guineas together? I also have a good-sized rabbit hutch -- would that work? I've heard they can be noisy -- will that be an issue? What are the benefits of guineas? The downside? Will appreciate any and all information.
