Are any of your silkie Roo's aggressive? I have a Porcelain De Uccle, who Percy constantly picks on. I understand establishing the pecking order, then going about your business as his brother Presley does, but not Percy. He DOES NOT stop pursuing Elvis, the Uccle. And my newest addition, Romeo, a 13 month old white silkie. Presley and Romeo battled, Romeo won, Presley walked away, and it was over. They get along fine. But Percy and Romeo battled, it was a tie, Romeo walked away. Percy was out for blood. Another fight, this time it was more vicious, Romeo won. Percy retreated, only to return 5 minutes later and the fight was on again. Once again, Romeo holds the title lol I assumed that they had finally established that Romeo was the older, dominant roo but Percy still will not accept not being the dominant male of the flock. Not wanting a blood bath, or for either one of my boys to get seriously injured, I went ahead and separated Romeo, he is now in a separate coop with my 2 chicks. He's the only chicken I have that has accepted the babies. Now, I know not to introduce the chicks to the flock until they are bigger and around the same size as the others. So I've been introducing them by keeping them in a large dog crate, and letting the other silkies come check them out. I know that in some cases it can be hard for males to get along, but it is possible. I'm hoping that each day will get better by slowly integrating Romeo with the boys. However, if it does not, it's no big deal to keep Romeo in with the chicks, and Percy and Presley can remain in their coop, and I can let them free range during different shifts.
