How is that for a unique thread title? WARNING! METRIC SYSTEM USER! 'Right, here's the deal: We are going to build a new coop and a new run, in a completely different place on our property. This is what we know: - The run will be HUGE. We have a triangle of roughly 20 by 20 by 20 metres on the far end of our property, which used to be forest but has recently had the trees cut down and is now used for nothing. What better place to put a new chicken run? - The run will basically have forest facing two sides, and the third facing our yard. Which also used to be forest. But which now is pretty big and flat, say 1/4 acre. (Edit: The yard is to the north of the run.) The run itself will not contain much, other than lots of leaves to scratch, the odd rock and sapling, and blueberries, by the look of it. - The coop will be on the north side of the run, to make it as close to our house as possible. It can be at any corner or in the middle of the side of the "triangle". - The coop will be rectangular and roughly 3 by 2 metres long and wide. One square meter of it will be a "human room", where we will enter the coop, and keep all the tools, food, fresh bedding etc. So the chickens will have about 2 by 2 metres to move on. - The roof will be slanted. From what I've read here, it's best to slant it away from the run. Does this apply to very large runs? (What we're trying to accomplish here is basically free ranging, but without poo on the neighbours lawn). - We only have five chickens - four hens and a roo. I want to make the coop big anyway. We might want to get more chickens in the future. - We live in southern Sweden. In extreme nights in extreme years, the temperature can drop to -25 degrees centigrade, minus windchill. This winter, the temperature usually ranged between +2 and -10. Minus windchill. In sommer days, it can get as hot as 30 degrees centigrade. Minus windchill. - We want a coop that won't overheat our chickens in the summer, but will keep them reasonably warm in winter. - We will insulate. A lot! And now, the questions! 1. Do I want the coop to face north-south or east-west? In other words, should the broadside of our building soak up sun, or avoid it? Remember, the walls and ceiling will be insulated. 2. Should the coop be in the shade or in direct sunlight? 3. Where should I put the roost? Remember, we wanted a slanted roof. My intuition tells me to put the roost under the highest edge of the ceiling. Naturally, the slant will slope from long wall to long wall. I'd like to put in a single long, two metre roost in there. A single roost means easier to clean the poop board, as well as, from what I've heard, less avian bickering. 4. How should I ventilate? Yes, I've read Pat's ventilation page. On five different occasions, I think. All of it. Yet, I still feel I can't quite wrap my head around this ventilation thing. I read somewhere on this board that with a slanted roof, you want to keep one slot open for ventilation along the higher side of the roof, and one directly opposite, along the lower side. The air would then naturally move between the two (heat raising, and all that). However, Pat's ventilation page tells me that I shouldn't put a roost directly under the ventilation slots. This means I can not put it where I wanted in point three, right? Right, that's it for now. I'll probably post more questions later, but my guts tell me I've given you enough to chew on for one evening. Any answer is, as always, greatly appreciated. Yours truly, Henrik Edit: No, one more question! 5: We have two BIG windows (0,7 my 1,4 metres, double plastic panes). Any ideas as to how and where to put them would be beautiriffic!
