Okay, so I currently have two coops one is a store bought 6 hen max, and the other is a 20 x 8, but is as of now just a run with a small dog house for laying, and a few roosts. The small one has 6 hens inside it and the large has 7 hens and a rooster. So in total 14 birds. 6 ameracauna hens,1 rooster, 2 rhode island reds, 2 Plymouth rock, 1 maran, and a small bantam. I need to know of they can all fit comfortably in the 20x8, after I build an actually coop inside of it. Also best way to introduce the 6 hens to the other 7,the rooster already knows both and happily goes in with both flocks, but the 6 have never met the 7. Thanks in advanced, sorry for such a long message!
