I finally found a good site on raising colony rabbits. Rabbit Talk is a forum, with a colony section. There are some experienced colony raisers who post. I have been up too late every night reading the archives. Lots to learn.
Here is something I just found. The site is Danish, written in English (sort of).
Rabbit hopping. Really, I had no idea. Short vids of rabbits in competition.
