Bostick, aart and finnie, thank you for the replies.
So thinking on this but you made valid points and I think Im probably going to orient my coop to the west side.  They wont get much direct sunlight but its scorching out there in the middle of summer so thats probably a good thing.  Just wasnt sure if chickens needed direct sun for vit D etc.  They will have some direct sun when they are out and about but that will probably be mostly on weekends when I can closely supervise.  When the leaves are off the trees they will get more sun. 
Also good point about stain.  I checked at Lowes and they have some really nice stains so I think Ill go that route.  Didnt realize they have pigmented stains that almost look like regular paint.  Now to get me and DH to agree on color. 
My other shed is just sitting on 4 4x6x8's stacked up.  Only one is partially in the ground.  They sit on about 4 to 6" of gravel though.  So it doesnt need to last 30 years.  DH says we are downsizing in 4 to 5 year.  I'll believe that when I see it.  Hope I can take my coop!
Got everything I need to get started at Lowes today.  Had to rent one of their pick up trucks to get it home and had to unload it myself, but it's all good, built some muscle. 
Learned a couple more things today:
1.  The Lowe's guy, Roland, was super helpful.
2.  4x8 pieces of plywood are not only heavy but super awkward for a 5' tall 115 pound women to carry.
3.  Cement blocks are also back breaking.
4.  Driving a 4x4 pick up truck for the first time-super fun.
5.  Sending pictures periodically to my DH who specifically told me not to do it alone----priceless 

  All he kept replying was "OMG"
The weather has turned a bit here so probably no digging today. 
I'll have dozens more questions so stay tuned and thank you all for your continued help and support.
