In my flock I have a 18 month Silkie roo, This past July I got 5 more hens(but turned out 3 hens and 2 roo's) In August I got 5 more hens. Having my Silkie roo being the head of the flock. With the first batch having 2 extra roo's, there have been only a couple of small dust-ups with with my Silkie. But yesterday OMG had the dynamics really changed. I figured that my smaller 2 roo's have become mature, but for some reason they are both waving a white flag in total surrender to Silkie, he now has complete control of all the hens, and my 2 roo's, Magoo and Hawkeye just stay in the coop and don't come out to eat their treats. Magoo was finally brave enough to come down the ramp (when I threw treats close enough for him) and started to eat, the hens rushed over also and started eating, then my Silkie practically flew across the run and landed on Magoo and chased Magoo back up the ramp and into the coop again, Silkie then stood guard at the coop door and wouldn't allow Magoo and Hawkeye out . Last night when I went to close the coop door there was Silkie standing guard at the entrance inside, and Magoo and Hawkeye were out in the run sitting on the stairs, I think they were hoping to get in the coop to sleep. I am somewhat concerned over this situation, because when my Silkie, an hour and half later went to bed and settled down Magoo and hawkeye both went into the coop and straight to the feed and water dished, Silkie jumped off his perch and again chases them outside into the run and again stood guard. They have been together for 5 months no problem and now from what I can figure out my Silkie has become the head master of all the hens and poor Magoo and Hawkeye are outcasts suddenly. After seeing for myself what my Silkie is doing, I had to take him out of the coop and bring him into the house for 15 minutes and the take him back out to the coop and Maggo and Hawkeye were settled on the top roosts. Silkie settled on his bottom roost. I really thought things were great with my flock, but now I believe that I may have to many roo's. Unfortunately I don't have the space to separate them all just yet.
