I’m trying to get clear design guidelines for a new coop and run for 4-6 chickens. We’re in Pasadena CA so get hot and dry summers with occasional freezing conditions overnight in the winter. We do have predator problems as well as our own dogs and cats so the chickens will be, for the most part, confined to the coop and run (They may have an occasional supervised play day out in the yard). The coop is going to be 16-20 sq ft and 4ft high, with three outside nest boxes attached to the side wall. I’m looking at using sand in coop and hay in the nesting boxes. The run will include 18 to 24” of space under the coop and an additional 30-40sq ft, 5-6ft high fully enclosed with 1/2 hardware cloth. Based on comments here, I’ll add sand to the run floor and make plenty of roost space available. I’d like to use water nipples under the coop to avoid dripping water inside the coop as some here have done, but wondered if water is needed inside the coop. Do they just go without water overnight or, like we do, traipse down to the “kitchen” for a late night drink? Should the food go under the coop as well or does it need to be inside? The chicken area is under an avocado tree which provides afternoon shade. I’m not planning on providing cover for the run other than growing grape vines over the top. Though we live in a near desert, we do get some pretty good rains. Do I need to cover part of the run or will they just go out, at least to water and feed. I’m sure there will be more questions especially when we actually get the birds but before cutting lumber I’d like to know that we’re on the right track.
