I’m doing the same thing! I do my “garden 20” (20 minutes ) of pulling weeds every day and use the weeds to feed my rabbits. BTW, I really dig the colony concept you use for raising rabbits. Personally, I tractor my rabbits, but my circumstances are different. I think your rabbit colony is really cool.

It's amazing how rabbits can turn vegetation into meat so much better than simply composting. With rabbits you get the meat and the fertility. We used to tractor the rabbits, it's better than the colony in many ways. Lots more control of the impact and easier to take care of them as well as harvest.
