About breeding boars
I'm hopeful but with questions as I'm trying to take this seriously.

My first 2 star boar, Jeltsin, is just hugging corner of its pen, even after bringing a mob to scare it. Got great big red exclamation mark and some noise but no attacking the fence, no running around or anything. It just runs at some intervals to grab a carrot and back to the corner it is. Luckily breeding did finally happen after placing the feed at Jeltsins feet and thus attracting mates to it. It has begun!

How often can a boar have a piggy? How long does a piggy take to grow? Does it take longer for starred ones to grow or should they be superior and actually grow faster?
Do starred ones eat more often than regular ones? Do they need more space, how many in a pen that's the size of max zoom out view?
Thanks!
