Since raising chickens may be too complicated, I am considering raising Guinea Pigs for meat.
That will not solve the egg problem.
I know they do that in other countries, and if you want to be technical, you are in another country, but I don't think that's really socially acceptable on this continent, at least the northern part of it.
Rabbits you could probably get away with. The meat is very lean.
Now as to chickens; there are two basic types: chickens raised for their meat, and chickens which produce eggs.
Technically again, they both do, but with fryers you don't have to care if you have a lot of males. And they can live more or less communally, because they will have a very Hobbesian existence.
Laying hens, on the other hand, will require little apartments and other modest appurtenances. They will provide a regular rental payment in return in the form of fresh eggs.
To a dedicated farmer, meat in the freezer always means that the contract you strike with the animals is a very hard bargain.
To someone more inclined to be a dilettante, having animals around and being on good terms with them might be preferable. You can pipe music in for the laying hens and be as friendly as you like.
But those whose destiny is the freezer, you don't want to get personal with.
Capybara.
They’re BIG guinea pigs, about the size of a small dog.
