I have been looking into black Javas also, but I don't even have a coop yet... hopefully in the Spring. As to the quality of the Java's, Duane Urch, owner of Urch Farms, is the pre-eminent breeder of black Javas. The Garfield Farm Museum outside of Chicago gets their stock from Mr. Urch and is leading the way in the preservation of the breed. You couldn't have picked a better source for your Javas, from what I understand, and Urch Farms is where I would go, as well, if I settle on them for my flock. Also, there's a guy associated with the farm museum named Pete Malmberg, who has started the nation's first Java Club, and emailed me back very promptly with helpful info when I asked a bunch of questions. Dont' know if the Java Club has a website or not, I found his email addy through a hyperlinked article on the farm museum's website -- Google for more info.
