Okay so I'm currently starting the building process of my hen house/chicken run, my question is this... Can 4 chickens and a duck live together? Is it best for them to be seperate? Will they be able to sleep in the hen house together or is seperate housing needed? What kind of adjustments need to be made to my floor plans for the coop/run? Is it the same living space ratio? I have my heart set on khaki campbells for my ducks and decided on astralorp chickens. If they can be house together, is there anything I should know or take into consideration before I get my flock? Does there poop pose any haazards to my 3 year old or any future children when I allow them to free range in my backyard?
