Good morning everyone my husband and I are new to chickens and we have converted our shed in to a coop and added a run 16x8 we are going to add another 8 feet so it will be 16x16 my shed is clear and there is a window and we are venting more but my question is the inside not sure how to design the inside we have 12 hens I think the can use 1 nesting box for 4 girls right? They seem to like to sit on there water and feeder so I was going to put branches so they can hang out . Any help and advise would be great thanks all
