Farm Animal Conundrum

[Tarrel]

Not sure why anyone would want to do that, unless it was the farmer doing so on a humane basis if they felt they were no longer able to look after them.

From a food source viewpoint, I'd recommend keeping and breeding small livestock (e.g chickens and rabbits). Easier to manage than larger animals, fewer storage issues following slaughter (basically you keep them alive until you're ready to eat them) and easier to keep secure. Indoors if necessary.
