Thank you for all of your suggestions. Here are our plans...
o coop window openings are sized for 2 "dump" windows that are currently in the basement
o will make a set of 2"x4" roosts for winter use
o we are investigating where to get clear or translucent tarp for the run, should provide a shelter from the snow and heat up the run a bit
o run does have a door and we enjoy being inside with our chicks, we sit with them quite often, I can't stand up in the run comfortably for a long period of time
o the run floor is dirt that we've covered with bark mulch, but the chicks seem to like to move the bark mulch into the back 1/3 of the run
Working on getting coop plans on my page and should have that done in a few days. Please send me any more suggestions you have...
