Barns and goat barns list meat, pelts and tallow but the chicken coop only lists the meat. It also produces eggs, which should be listed as well. Of course, like many other buildings I am aware they make waste too, but this is not listed as a produced item in any of them.
Oddly, the pub identifies beer in the items produced section of its UI even though it doesn’t actually produce it. It just consumes it much like the marketplace stocks and consumes other items, but that is another matter not entirely related to this post.
