Hmm, this is huge, i must say. This is a kind of hard, gritty work that reminds me of a time o had to construct the pen for my goats and also the rabbit. I had to go scan through my vicinity for a tree that can do quite the same job as buying outside. It wasn't an easy task, but I had to do it to safe costs. I brought the tree down and cut it into a piece with the help of a neighbour around, then proceeded to pen construction.
