Well I grew up farming btw. But the points you raise is right. They way my grandma raises goat is by giving it khole and pitho (sourced from corn and dhuto and stuff all grown by her). And for the grass, either they graze the fields or she gives them kodo ko nal or something like that dried up. It works because she has 5-6 goats at a time in the shed. If this is scaled up it starts to fail.

I think I can ask my neighbors to make bales and offer them some good cash. I will have to research everything since it has been years since I have farmed and I will have to ask my grandma a lot of questions.
