We have one bantam roo who is very very very small. We just adopted a silkie roo a little over a week ago. We have 6 hens currently for the two of them to share. I introduced them two days ago and my bantam is picking on the silkie. The silkie is very submissive and any time the bantam comes over he just lays down or runs away. We havent had a super serious fight but how long do I leave them like this?
