We have a "coop des gras" for our 20 hens and two roos. It is insulated, has six windows, took wayyy to long to build and wayyy to much $$$. We are LOVING our fresh eggs, however. I am researching / considering cornish x for meat. Slaughtering our excess roos has been great for our dog (fed on a raw meat/bones diet) but not that satisfactory for those of us doing all the work! I am not in the market to build another large/expensive/difficult coop. What is the minimum I would need to provide cornish x to keep them safe and happy? I AM okay with providing a moveable tractor/enclosure to give them grazing room.
