So, I have a flock of 15 birds; 13 hens and 2 roosters. I have two 4-year-old Barred Rock hens, four 2-year-old White Leghorn hens, and then nine 25-week-old birds, 3 Partridge Rock and 4 Light Brahma hens, and 2 Light Brahma roosters. At first, the pecking order was by age, the younger birds at the bottom with my larger rooster the dominant one over the smaller, more submissive one. I recently brought 4 of the new hens (2 PR and 2 LB) and the dominant rooster to show at the fair. They were there for 4 days. I just brought them home today, and they seem to be resorting the pecking order. My dominant roo easily took over from the submissive one, like before, but I saw him fighting with one of my Barred Rocks and two of my Leghorns. Not sure who won though. When I left, he was crowing. Not sure if that means he won, because he did it before I brought him to the fair too. Do they even remember each other? Treating each other like new birds? How should I expect it to turn out, the way it was before, or my dominant rooster in charge? I've only done this with hens before, and nothing has ever changed.
