I had an original flock that I got at about 8-10 weeks old with a few roos and a few hens in it. I let them grow up for about 8-10 more weeks and then got a second larger flock of 8-10 weeks old that I eventually integrated with the old flock. Now the old flock is 20-24 weeks old and the new flock is 12-16 weeks old. There's the background info. My dominant roo (or any of the roos) in the older flock has never once mated with any of the hens (that I've seen, although I've seen plenty of feather pulling without any real mating attempts). Today I'm watching my flock and notice the dominant roo of the younger flock walk over to a very young looking hen of the young flock (she seems less than 12 weeks, she is tiny compared to the others) and step on her back and grab her head feathers and gets on with business. My older, dominant roo didn't even bother to do anything about this!! It's extremely obvious who the males and females are in the flock by now and it's also very apparent who is at the top of the pecking order, which is why I'm so confused. Why haven't my older roos figured anything out yet? I'm also still wondering where my eggs are. They are nearly 6 months old and not a single egg. Lastly, I plan on separating all my hens and roos and taking the hens with me to my new house and leaving the roos at my parents' house. If I choose to bring a roo or two along with me at some point, would I have to go through the quarantine process all over again with the roos? Thanks!
