Your run is absolutely adorable!!! I like it! Now for the coop....that pophole of sorts on the right side...I take it that is no longer used, correct? If my guess is right, then I'd wall that off completely...too much draft can flow through there. The roost bar in the back on that photo...I don't know what breed girls you have but you might move it just slightly forward from that back wall...looks a little 'close'. Can you tell me what that large dowel-type rod is in the forefront? If it was/is a roost bar...get rid of it. It's directly over your nesting boxes...yikes!
