Theresa,
One source is Eggbid.com and probably a better source is McMurray Hatchery. They have pairs listed. Before you receive these birds, you must have a pen established so that they become accustomed to their surrondings. This takes about 2-3 weeks. It is a labor of love. If you are willing to travel, there is a gentleman here in Indiana that have a pair of black one for sell last September. I could call and check for you.
Hope this helps.
