Hello all! I've just started my little flock not that long ago and they are in need of a run. I have a wood framed 12ft long x 8ft wide x 4ft high priced out. It'll be really easy to construct due to the dimensions. Now, I know it'll the even easier and cheaper (which means I can make the run larger) if I use the metal fence posts instead of a wood frame. The thing is I'm not sure how I would create a gate to get in and out. Any suggestions?
