I have two brown leghorn pullets who are about 9 weeks old and then six or seven GLW pullets who are 14 weeks old. I am taking the roos, seven in total, to the Amish this weekend and would like to integrate the flock soon. At the moment the leghorns are living with the ducks who they have grown up with. But seeing as the ducks are both boys I don't want any attempt at breeding to happen between the ducks and pullets so they will be separated. I also am processing our Cornish Rock X this week, probably Friday. My question is should I wait to integrate or should all the changes and the pecking order being re-established be a good time to slip the two pullets in? The run is 25x35 so I don't think that should be a problem size wise, and the coop 10x8. I was going to build a small box to place in there in case the GLW start to pick on the leghorns and they can run in there. What do you all think?
