I am looking to keep about 15-20 Silkie Bantams and around 20 or so Suffolks or another breed and I was wondering do I need to separate them. Space is no issue and I have a half acre field which is not used for anything so was thinking of keeping chickens on it. My question is Do I Need to segregate them and keep them in two different coops, or keep them in one big run with a converted shed as a coop?
