Was mowing the yard the other day and found an excellent way to explain where to put your coop and why. Consider this photo........
Shaded area on the left is on the north side of this row of pine trees. On a day when it was about 70 degrees out, it may have been at least 10 degrees cooler in the shade than it was on the right side of the trees in the full sun. Ground in the shade is moist, damp or wet most of the year, and especially so in winter. That is the last place snow and ice will melt and it is exposed to the cold north winds of winter.
By comparison, right side is exposed full on to the winter sun and is high and dry most of the time, far and away warmer all year and protected from the cold north wind by the row of trees.
Two locations, no more than 20 feet apart. One on the right an excellent place to park the chicken house. One on the left a miserable place. If all you had to work with was the shaded one on the left, my recommendation would be "don't bother".
