What kind of rabbit is that? I’d love to see more pictures of your setup. Here are a couple pictures of the rabbit tractors I built last year. I’m new to rabbits and it helps to see what other people are doing.

So we have three of these tractors that we use as needed. Right now the buck is separated from the 2 does, who are in a stationary enclosure because they have babies that are not yet weaned, and the stationary enclosure is built more securely, for predators. When the babies are weaned, they first go into a raised cage (shown), then into a tractor. And when the does dont have babies to nurse, we put them in a tractor. This is working for us, but i'm sure there are many different options. I think they are californians? Hope this helps. 
Thanks for sharing. It’s nice to see how someone else does it. I do mine a little different. I built more robust tractors and let all the breeding and nursing going on in the tractor then I built grow out cages. Honestly, I haven’t had very many rabbits to eat personally. People have been buying them up before they get old enough to process.
Thats a good problem to have!
