http://www.carolinabackyards.com/Chickens.html My husband and I just bought this coop (naturally right before I found this website.) We don't have our hens yet. How many would you put in a coop that size? What about a rooster? Also, If I put the coop in my yard that's completely fenced in, do I need a run? If so, should that be purchased as well, or are those easy to build? (My husband is great at building things but doesn't have a whole lot of time) Also, when you buy a coop, has anyone "altered" theirs as they got more chickens, or do you have to keep buying new coops? Thanks!!
