When it comes to deciding which type of chicken is best for your homestead, it really depends on what your purpose is. Do you want a chicken that will provide you with both eggs and meat, or are you looking to specialize?
Meat kings are bred just for meat. They are a fast-growing chicken, so fast that they are ready to be butchered within 6 weeks.
With dual-purpose chickens, you get the best of both worlds. You have a source of eggs and meat. In most cases, you will raise a chicken like this primarily for eggs during its more productive laying years and then cull it for meat.
Which chicken is best for your homestead is going to be best for what you are looking for.
