We will be building a new 6'x6' shed-style coop this spring. It will be going on the south side of the house in a space that is approx 15'x15'. If we put the coop closer to the house it will get full sun all year round, which may be nice in the winter. If we put it near the 6' fence, they will get very little direct sun in the winter as the shadow cast by the fence is 8-10 feet long. We regularly get daytime temps around 10 deg. F in the winter and temps near 90 deg. F in the summertime. We plan on having plenty of windows and ventilation in the coop and the chickens will free range in the back yard for most of the day once the snow melts. So, sunny side or shady side?
