I am planning to build an a frame coop based on some pictures I found in the coop section. But before I get started I have some questions for the more experienced...which at this point is pretty much anyone who has ever built a coop! I live in Oregon so we have mild winters (and summers) but we do occasional get snow in winter and a day or three over 100 degrees in late summer. I think I have ventilation figured out and my plan allows enough floor space for my maximun occupancy of five hens. (So far) I am planning to insulate the floor of the coop because the coop will be raised up 2 feet from the ground and the east wind does travel up the hillside in that part of the yard in winter. I am planning to make sure the coop will have good ventilating in warm weather and close up enough to still be vented and draft free in winter. I don't plan on heating (unless its FREEZING COLD) so should I insulating the sides or is making sure the coop draft free enough? I have gathered together everything I could reuse or recycle and only need hardware and 2x4's so I plan to starting to build the next time it's not raining and over 50 degrees. Any help during the planning phase would be appreciated.
