I currently have 20, 10 week old birds (14 chickens and 6 guineas). The guineas have started picking on the chickens so we were going to take the chickens out of their current coop and leave the guineas in there. I was hoping to build a medium or small sized pole barn to house at least 50 chickens, have a storage space for food and shavings, brooder pen (not necessary), nesting boxes, and breeding pens. Now the main thing I would like to know is how to go about all of this, what should I focus on, like what type of flooring to use, or basic interior layout ideas. If someone could give me a price estimate that would be great, I would not likely need to hire a contractor because I can do most construction on my own.
