Turtlehead (Leslie) from the HT rabbit forum has a successful rabbit colony in WV. I've followed her venture from the very beginning and know that she had to work hard to deal with a number of serious problems that came up in the first couple of years she had her colony. Here is a link to her blog. I think everyone interested in rabbit colonies can learn from her experiences. Great photos too!
