I am in the process of setting up my breeding pens. So far I have 5 6x20 ft pens, I am going to have tin and some netting on the tops and I'm considering putting some tin around the bottoms to keep the Roos from fighting and keeping the dogs from bothering the chickens. The main issue I'm having is the housing. I'm a bit stumped on it. Does anyone have any photos of how they have their breeding pens set up? Please!
