How great to have a coop large enough for a brooder and chicken jail! Is the chicken jail for a chicken that is picking on others or a chicken that is getting picked on? My coop is only half finished, I'm months away from getting my first chicks, and I'm already haunting Craigslist for a small, inexpensive but well-built coop (not so easy to come by) to use when I need to isolate a chicken for one reason or another. I did lots of research before deciding on the best way I could use the space I have for the coop and run, but I can already tell that this will continue to be a learning experience and I'll have to make changes as I go.
Congrats on starting the framing! It is so satisfying to see it go up. I think that and painting are the most gratifying steps of any project like this.
