That's the most creative use of an unfortunate incident I've ever seen. The coop itself is amazingly adorable and functional. I'm soooo impressed. How fun for all of you.
I love the photo of the children sitting on the deck. I hope they're tossing treats down to those chickens! You said five oldest. How many do you have? I'm always in awe and completely jealous of anyone with a large family because that's what I wanted (but didn't get).
I have a question about the flooring.. I see that you only have a wire floor.. which looks awesome for not having to buy bedding and for easy cleaning... (excuse my newbie questions) are the chickens ok with not having a soft floor? It doesn't hurt thier feet? I see you are in Valporaiso, so I'm assuming Valpo Indiana.. by not having a solid floor, wont an updraft in the winter make for chilly chicken bums?
