Kiwiegg I did put the skids on the concrete pilings.  It made it really easy to level the floor that way and it gives the chickens a place to get out of the sun if they like.  I definitely do not worry about it blowing over.  You can always put some lag screws in through the holes in the metal brackets in the pilings if you are really worried but the coop weighs a lot!  
  Like I said to Gryeyes earlier though, I would stick to the gabled roof in the plans though unless you really know what you are doing for the sloped roof.  I think we really could have gone with a smaller slope on the roof too but I will see how it does this winter and how the snow slides off of it.  I might be glad that we did the 20 degree slope.  
Heather I am done building for a while!  
  I do still have a few things to do on the this one.  Finishing up some of the trim work and I really want to do the PVC feeders inside the coop.  The chickens keep knocking over the feeders in the coop and I want to do a better roost.  I just stuck one up quickly so that they would have one but I would like to do a longer one.  I still have to put the board up in front of the nest boxes inside so that they will stop knocking all of the pine shavings out of them.
vnploves chickens I will get a picture from the back so that you can see the roof and of the inside after I make the improvements that I want to do.  Probably won't get to the improvements this weekend since I have to go food shopping for the horses and I would like to get a ride in if the weather cooperates.  
I would like to thank everyone for the kudos and the encouragement, this project has definitely given me the courage to think of other things I thought I couldn't do but probably can!
ETA - Kiwiegg I am really glad that I put the nest boxes on the outside.  It does save a lot of floor space.  I only have eight chickens now but I am dreaming of more! 
   It was easy to modify the outside nest boxes from one of the other plans to five exterior nest boxes for this one.
