PiecingItTogether, did you build your calf hutch coop? If you did, I'd love to see it. The calf hutches sound like they'd have the advantage of being easy to clean because they're plastic, but I've never actually seen what a calf hutch converted into a coop looks like.
Edit: I found one...
I'm sorry to necro this thread, but I was thinking of building a coop this way and I'm really curious how it's working for you!
Somebody told me that it's important to make sure the type of plastic used won't emit any fumes when exposed to sunlight and warm days, because birds are a lot more...
