Great use of recycled materials! I read through your article twice, but I never saw where you mentioned what size coop you were making (length x width).
You mentioned where you got your initial plans but I did not try to go to that site to see if there was only one set of plans or if there were multiple different types of coops to choose from.
It looks like you used chicken wire on your coop/run. Chicken wire is very easy for raccoons to tear through.
I like your idea of using one of the nest boxes for storage. Did you include a way to close it off to the chickens? Just in case they didn't get the memo!
Thanks for sharing your coop. I hope you are enjoying your chickens!
