There's a lot going on here
I reckon that, given you're going to get all the animals you want eventually, you will have a much more pleasant life if you get the goats first
(PS it is a known fact that the female half of a partnership's votes count for at least two - you know the quote 'cats and women will do as they please and dogs and men might as well relax and get used to the idea')
Goats will need strong, high fences and a shelter. Pigs the same, though the fences won't need to be as high.
In fact, if it were my land, I'd get more chickens first while I sorted out the fences and shelters
