Good morning and HAPPY FRIDAY. I currently have 8 BO hens and 1 BO roo in a 6ft x 8ftx(8 feet tall) coop attached to a 20ft x 20ft run. I would like to add a few chickens...different breeds. Do I have enough space for a few more? I am building a small coop and run to house my "hatched, growing up birds" that will be; coop 4ft x 6ft and a run that will be 10x10. However, I would like to be able to integrate all the grown birds together. Just trying to be prepared. Any advise is appreciated.
