This coop looks lovely, and I can appreciate the thought and the work that went into it, but I have several issues with the design. My first impression was that the predator protections were pretty overkill unless you're trying to keep out grizzlies. But, whatever, that doesn't hurt anyone. However, I'd be worried about the paint on the interior. Birds have pretty fragile respiratory systems, and the fumes from most paints are toxic to them, especially when relatively fresh. Also, chickens tend to pick at paint and ingest flakes of it, particularly when they're bored waiting to be let out of the coop. Another issue is the hospital enclosure. It may work for an injured bird, but not for quarantining a sick one. In addition, while the chandelier is charming, it worries me. While this may not be too big an issue for large, round birds, if I had any of the smaller, flightier breeds (or even youngish pullets) I'd be worried about them trying to fly up and perch on the chandelier, which could knock it down and start a fire. In a similar vein, the roost situation leaves much to be desired IMO, the stair setup seems liable to have birds defecating on the backs of their flockmates, which may lead to birds roosting in the rafters, meaning they'd be caught in the ventilation drafts and be colder, as well as putting the chandelier in danger. I might be overly critical, but with this build I'd be more worried about the chickens causing trouble than about the predators eating them.
