A few Coop design questions

Hi there. The main section of my main coop (because I have THREE coops...lol) is 6 x 8, like yours. Based on me designing mine incorrectly, I would run your roosts across the 6 foot span if possible, and you'll need to run two for 10-12 birds. You can stagger them, like two rungs on a ladder. I ran my roosts along the 8 ft. span, and that made space really tight for flying/hopping down (my roosts and dropping boards take up about 2.5 feet, which only leaves 3.5 feet depth...not so good).

You will want at least 10 sq. feet per bird in the RUN...more if you can. The more space they have to run around outside, the better! You can always do temporay fencing...just a few metal posts and chicken wire until you can get something more permanent in place.

A cut out window is fine! As you mentioned, cover it with strong wire of some kind. You can use plexiglass or even clear vinyl (sold at fabric stores to cover picnic tables and such) to cover your windows in winter time. Good luck with your chickens!

 

Probably the easiest thing to do is to put a 2x4 across. I used tree limbs. Some people have pretty strong opinions on this, but I find it does not matter if the narrow side or wide side is up. They will use them either way. I suggest sanding the sharp corners, partly for comfort of the feet but my real concern here is to remove splinters.

I suggest making them removable just for convenience sake. It's come in handy for me a few times. I'll show what I did.

 

Read up on ventilation.

 

I agree! You will want to cut out some ventilation openings as well (cover these in hardware cloth). You'll want these up high, and if possible, NOT on the wall(s) of the prevailing winter wind(s). Or instead of wire, check out yard sales, thrift stores that carry building supplies, habitat restores, etc. to find old floor/wall registers that are closeable. Just cut your vent openings the size of the vents you find and screw then in place. It's nice to have closeable ventilation if you're in an area that sometimes gets severe overnight weather events in winter. If you're not though, just opt for wire over the openings.

* Oh...and I would opt for 2x4s or 2x3s for that span...nice and sturdy. I do have thick (minimum 3 inch diameter) branches for perch variety in some of my runs (as well as 2x4s). But I prefer 2x4s or similar lumber cuts because they're easy to scrape if they get poop on them...branches are NOT. I don't care for round roosts because chickens tend to rest on their feet rather than grip a perch like a parrot or wild bird...

 

We just completed (and converted) an 8 x 12 shed. We have two sections - one for our two bantams and one for the seven standards. Ventilation was our main concern. I see tha you are in Utah. It may be that you definitely need good ventilation up high (due to a cooler climate) and have received some excellent advice from previous posters. Our weather dictates more ventilation due to heat. We installed four fairly large windows in our shed (that were purchased off of Craigslist for next to nothing). Instead of screens, they're outfitted with hardware cloth. Also, we constructed a hardware cloth wall (with matching hardware cloth door) just inside the double shed doors. This allows us to keep the front doors open (rendering the structure a three-sided coop) during periods of excessive heat, yet keep predators out. -ventilation is critical. -better to have too much that can be closed than not enough, IMO.
