Hi Mister B,
It is a safety fence playpen for my young pullets who are now 3 months old. My hubby built it as a temp fix until he can build something else. We've been using it for about 3 weeks now. They are only in it while I am home and during the day. We used a roll of safety fence, 9 6ft fence posts, zip ties to secure the fence to the fence posts and left one loose for the "gate". (total cost $28.00). I am thinking we need some sort of garden stake to secure the fence to the ground as I am sure they will figure out they can go under it at some point. I'm also wondering what is going to happen when they figure out they can fly over it. So it is only a temporary playpen. My husband is working on making an addition to the run and coop we already have.
