I am debating between building my own coop versus buying it from from someone from CL. I am looking to house two hens (probably Rhode Island Red). Dimension of the coop is 4'x6'x6'. I live in San Diego where we get 10" of rain a year on average. In the summer, it rarely ever get above 90. Does the coop look like it have adequate ventilation? Does it look secure enough? I don't have racoons where I live but there are possums. I don't have any pictures of the interior of the coop but was told that there are 6 nesting boxes. (I am waiting to hear back from the seller regarding some photos of the interior.) The seller wants $285 for the coop and $50 to deliver it from Santa Ana which is 80 miles one way. Is this a good deal or should I attempt at building one myself? Thank you.
