Here's a question. I have bantam roosters And I had them out foraging with the big girls yesterday. They were in seperate areas of the yard for the most part than both of my little boys ran over and attacked three of my "hens " totally ignoring the other 7 girls. In fact those 7 sat down. The others postured up. I am assuming those 3 are roosters. The bantams are older by a week or so. The big girls are 6 weeks old.
