I made several large enclosures[at least 7x7 large floor tiles] and average about 12+boars in each as a 'max'...that's more than enough stock of 2-** boars @ 4 hanks of meat per to fill my needs. No wacky breeding tower, just open pens with enough space. In the open areas nearby, I plant and tend crops while the breeding process continues, which is close enough to hear the audible cues of the process steps. There's more than enough wild raspberries nearby to sustain the entire facility, the veggies are for human consumption. I like visiting "HogFarm"....it's a chill relaxing spot in a meadow, next to a creek.

Right now, l'm in the process of determining the maximum obtainable count of 2-** wolves in my 12x12 pen[12 4x2 stone walls, so I guess 24x24]; it gonna be a large pack...give breeding stock enough space to get 5 tiles between groups/clusters is my secret[hence 7x7 as a min]. When I feed, I spread clusters of ~5 food units around in the corners to help spread them out...
