We are planning to build a chicken coop and would like idea/plans. We are thinking of raising about 4 different breeds. I'd like a coop that I can divide long wise with 3 or 4 different entrances and a long run that I can also divide into 3 or 4 different runs. I want one part big enough to house most of my hens (all breeds together). Maybe about 12 for our own personal eggs. And then the other 2 or 3 will be a lot smaller and big enough to house one roo and maybe 3 hens. This will be used as our breeding pens. We were thinking of buying a book to help us. Do you have a book you can recommend?
