Snow covered coop and run

Last night it snowed.  We awoke to a beautiful winter wonderland.  I brought a broom out and dusted off the blanket of snow that covered the run.  It slid off with ease.  When I let the chickens out this morning they were curious about the white visitor from the sky.  They looked out at the end of the run and then returned to eating the scratch that I had just strewn across the run.  Covered and dry, they went along with their daily business.  I quickly peeked into the coop, and it was dry as a bone.  The snow should continue for the next three days.  I wonder if the chickens will even notice?
