Okay, so a tile counts as 1 food unit. Is this per day, or 1 unit total forever?
I have 3 bulls in a 6x6 pen, if it's 1 unit per day then this would mean that I don't have to feed them, but if it's 1 unit total I will have to feed them.
Also does it matter if I feed bulls low quality fodder, or will this lower their quality?
