Wow, that's so interesting. I would love to raise them in a more open rabbit run type situation. Have looked into it but haven't seen a system yet that seems to work for me. You should do a post on social fabric of the colony, that would be awesome. I saw a documentary about that once, can't remember the name of it. Thanks for your story, upvote and follow.
Here's a cool video of rabbits in an open pen.
