Will you paint the inside? My coop looked nice and fresh for a while but that chipboard and planks will really hold dust, feathers and creepy crawlies.
I just finished making my own whitewash and painting the whole insides. Lots of work banishing cobwebs and dust after the fact, so maybe paint inside before they move in. I had to lock my hens out of their yard while I painted and that was a real pain.
NICE LOOKING COOP BY THE WAY! NICE JOB!
