First off, My Frail Boars sounds like it needs to be followed up with Last week on 'My Frail Boars' with a rundown on the plot so far.

Secondly, unless you are breeding 2-star pigs, don't bother. My opinion obviously but i found it a waste of time. If you continue to do so though, try making bonfires at the corners of the pen, just find a nice proximity.

Bonfires i swear are really useful in so many situations.
