Chi I def agree with the muscovies, no one will know about them. The bad thing about the cow (cut and carry system) is that everyone will know about it, and then they dob you in with the council. Goats are better in this regard, they are less noisy. Milking animals have a huge advantage, which is a continuous supply of fat and milk every single day. They are a lot of work, especially in cut and carry systems (and you have to walk them too), but the reasons why humans did it for such a long time is exactly that.
I don't agree with the rabbit: even in suburbia and in many cities, you'll get enough greens to feed a rabbit. It is the source of protein in tough times. Quinoa has very little protein compared to rabbit meat and can be harvested once a year. If you need to use your square meters wisely, the rabbit wins big time, also because this is a cut-and- carry system. I know that many people here lean towards plant-based foods, but onc the trucks stop rolling this is a very luxury option, just run the figures.
