It’s against my house it’s just a 4x4 dome pen I’m leveling out a new spot on the other side of my sidewalk to put 3 pens the ground stays to wet where it’s at right now.I would try to contact the club president of secretary. Odds are they have a website or something on facebook.
What side of wall is that pen on? I try to move mine around a lot to protect ground, keep birds in fresh eats, and presumably to control intestinal worm issues. Concrete would be nice when ground gets soft.
