I am thinking of getting pre-made coop for couple of reasons. First, I don't have scrap lumber material to build it cheap. If I buy everything from the store it will be expensive. Second, I don't have time to do the coop from scratch. So I am looking for a coop that would house 4-6 large chickens such as New Jersey black giant and Rhode Island Red. Hopefully I can get away with one that is $500 or below (including shipping).
