Given how many variables there are in determining the necessary space per hen, I thought I should give my specifics. Can I keep 5 barred rocks and 2 Ameracaunas in a 4x4 coop that has open access to a 9x6 covered run? They will have 4 nesting boxes and 7-8 feet of roosting space. They will be fed outside of the coop. They will also have occasional access (on weekends when I can supervise) to my garden area (about 12x40 feet). I live in south florida so snow is not a problem. Oh, also, when can my chicks move on outside? They are two weeks old right now. I'm a first timer at chicken keeping and would love everyone's input. Thanks!
