Pig pens are shelters for pigs. The first pen is unlocked at experience level 10.
Appearance
The pen is a fenced square, on muddy ground, along with a manger. However, pigs are fed individually with pig feed and do not use the manger.
Building
Each pen costs 150 
and can hold up to five pigs. The second pen is unlocked at level 18, and the last one at level 32. Building them takes no time.
Strategy tips
- If you have some object obscuring your view of the pigs tap on the pen. If the harvest or feed icon are in color then you can harvest or feed at least one pig.
