I'm inheriting a coop from a friend (we're first-timers), and I know the rule of 4 square feet per chicken. That said, I measured the entire space (coop and attached run), so Im honestly unsure of the actual coop's size. It won't get delivered until next week sometime so I can't measure again. Obviously I can wait until it arrives to decide how many birds we're getting, but would love some thoughts. Are gravitating toward non-bantam breeds. The entire coop/run here is 6 feet long and 4 feet wide. I didn't measure the height. Sorry for the picture. My friend snapped it, as the coop is just sitting in her driveway. Thanks!
