My local craiglist has a number of ads for ready made chicken coops or tractors. Most of them way over estimate how many hens there coops will house. When one ad claimed that his 4x4 coop could house 12 chickens, I thought it was a typo and he/she meant to say 1-2 chickens. But then the same person posted another ad claiming it housed 12-16 hens. (BTW, a good portion of that space is taken up by 4 nests) It makes me crazy, the primary people who would be buying those coops would be novice backyard chicken farmers. And here this guy is telling newbies to stuff 12-16 birds in less space then if they were in battery cages. What would you do? Just ignore those ads?
