I do not have a coop built...yet, but I have some time as the eggs are just at day 5 maybe 6. I've been trying to do some major homework before our final design. Any thoughts on the following would be greatly appreciated.If it gets really hot in the hen shed (mine is in full sun unfortunately) I will run a floor fan especially at night pointed up to the ceiling in the hot weather (deflects off the ceiling rather than directly on the birds). My birds aren't confined indoors, so it's not a big issue as they'll not stay inside anyhow - they just come in to lay eggs and roost at night. If they were confined indoors I still think this works well. It is a fan that is rated for "workshop" or garage/industrial so it has an enclosed motor to keep the dust out. Similar to this (I got mine at Menards)http://www.menards.com/main/heating...14-industrial-floor-fan/p-2381241-c-12728.htm
I use wood shavings in the shed. When I clean it out, they go right outside the door into the run as part of the outdoor deep litter. I have read that sand can be quite a vector for disease - and even for cocci during certain conditions. I like to keep my outdoor run healthy and it makes good healthy ground to do a deep litter outdoors. Those shaving are never wasted and they make the best soil full of bugs and goodies for the birds to dig through in the run. I have written about this before and getting wood chips for the outdoor run from tree services. If you "search this thread" above the thread title (rather than searching all of byc) I imagine you'll find some of those posts as I'm kind of a broken record on that.
I would like to have 2 sections in my coop, (just a chicken wire wall with a screen door for me to get through) open to one another the majority of the time, but that can be blocked off from one another if I'm hatching/introducing new chicks, have one that's being picked on, crazy rooster, etc. Anyone close to 135 and Thompson? Just curious. Thank you for any input you have. See Below

I'm going to post some photos of my shed converted to coop for you. And some thoughts on some of your other questions. See above in red.
I wanted to show you how we did our shed and nest boxes and it might give you some ideas.
I have an area that is the "people" part that the chickens can't get into. That way I can go in the door and not have chickens under foot. I also use that as a little storage area.
My nest boxes are accessible from the people side so I can gather them in there, out of the weather, without having to go on the chicken side.
The chicken part is divided into 2 areas so I can either close one off or keep it open depending on if I have a need. I used one side for the mamma broody or for brooding chicks if I brood w/out a broody. I could also do like you're doing and raise a batch of meat birds or whatever on that side.
There is now a 2nd pop door on that side that leads out to the kennel run. I just divide the run with temporary fencing and then when I don't need the divided area I can open it up so everyone can have the larger run.
Here is what it looks like:
Looking in from outside. You can see the nest box to the right.
On the people side: The box has a turning latch so that no critters can get in it and go through. (I leave the front doors clipped open all spring, summer and fall so the interior has to be predator proof.)
On the chicken side:
Standing in the people entry looking in. The divider gate is open so that they are accessing the whole area in this photo. You can see it just to the left of the chicken. That door is raised up with a short wall underneith so that it can swing without hitting the bedding.
All interior wall and door framing is framed so that there is not a large expanse of wire that an animal could push into easily. The smaller frames make it more predator proof. (Nest box over there to the left.)
Here is mamma broody using the right side with that interior gate shut behind her. (This was in January with temps in the teens and 20s. Mamma did a great job.)
[oops...a huge broody poop in the corner...better ignore that

Outside with the temporary divider. Using plastic netting you can just clip it up or use temporary stakes from the farm store and then remove when no longer needed. I found that I had to go all the way up to the top, however, as the "man" would get right out of the 4 ft. high fence so I had to hang a second one above. Used eye hooks screwed into the shed on the one end and clips on the kennel side.
This side now has a 2nd pop door so that they can enter it from the "broody side". It wasn't installed in this photo.
Rolled back.
Here it is with the pop door showing and the temp fence down.
You can see both pop doors here. (Both of them are on a timer to open and shut.)
The newest "chicken children" using the new pop door entrance earlier this summer.
I don't have a great photo from farther back so you can see where this second door is. I guess I need to get some new photos.
