We just got our first 9 chicks in March/April. We were hoping one would be a roo, but got all hens. Our ladies are 10-11 weeks old. We are getting a Barred Rock Roo delivered today, he is 9-10 weeks old. Is there anything we need to do to introduce. How should we go about introducing, sleeping arrangements, changes we need to make to accommodate him in the coop.
