My coop is 4 ft x 8 ft and has six nesting boxes with perching bars. The run is 24 x 8 completely covered and we have a larg uncovered run they have access during the day when we are home. (see photo below) I currently have 12 hens and one roo. I have ordered 8 more hens and another roo. I plan on building an additional coop with it's own large run and expande the outisde yard and join the 2. Of course I would keep the flocks separate until about the same size. My questions are: 1. What are the odds the roos will get along - Barred Rock (existing) and Salmon Faverole (new) 2. What are the odds everyone will end up all in the same coop - making the expense of building an additional one a waste. 3. Should I just expande the run and outside yard? Thanks in advance!
