My parents in India always had water buffalo and chicken on the property. Water buffalo milk is richer & creamier than cow milk. The chicken foraged on the property and I still remember the delicious tasting eggs.
I live in a suburb of Boston, we have 2.5 acres and abut a huge wilderness area. Chickens are allowed, goats would be too I think, but I’m pretty sure we can’t have larger farm animals. So no water buffalo for us! But the eggs are awesome
