I have 9 new chickens and 3 already so I built a new coop. I would appreciate any suggestions. I included pictures of my old coop for my 3 girls which did really well this winter. I built 4 nesting boxes from an old shelf and will block off about 1-2 feet of the inside of the coop for me to store a few things and gather the eggs. I'm planning on putting a small door on the side and attaching the old run to the new coop but I think I need to make it much larger for 12 chickens. They free range when I'm home but need to be in the run while I'm at work. The new shed is 7 ft by 7 ft but I took blocked off about 1-2 feet of that space. Any suggestions?
