Just a note on the rabbits if you do decide to breed them, they're STRICTLY herbivores. I don't keep them myself but used to live in a house with a woman who always had two (would adopt another when the older one passed). I know they'll eat their own pellets afterward and digest them twice, so that's pretty weird. But I do remember that the woman was very adamant about only feeding timothy hay and a mix of leafy greens/veggies. Their digestive tract is built to handle grasses and other plant material.

Beautiful burm! Just figured I'd chime in on the rabbits bit. Don't have experience with any of the other concerns, haha
