Aww Lynzi, that's what I thought too. They are about 17 weeks old now. At first I thought maybe the Black Silkie is a rooster too? And Fredo the rooster is "protecting" the frizzle sizzle hen. It doesn't seem to be so because the silkie is not near the frizzle hen when Fredo pecks at the black silkie. Fredo and Chicken Nugget are silkie cochin crosses and they fly, they roost. When they fly up to the "roost", it's a cardboard insert from Christmas wrap, the little black silkie cries to them. It tries to climb up the stick to get up to them but it tips over. It's like the black silkie is the "third wheel" in the mix. When they go into the kitchen, they tend to stay in their large long box. As soon as I put the little black silkie down, they all crowd together in one tiny box in the corner of the large box. They are free to go anywhere but they just stay like that. Fredo in front, watching out, then Nugget, and deepest in the box the black silkie. The black silkie is the only purebred one, and it's much smaller than the other two. I thought if they all hatch together they will be best friends? If the other two are out alone, they will fly out of the large box and walk around the kitchen. Could they be instinctively trying to protect the black silkie because it's a smaller bird?
One of our city neighbors has a lovely rooster. He lives with dogs, no hens. He adores being picked up and petted. When they dogs start to bark, he crows. Very adorable rooster, a bantam, not a silkie. This bird is handled daily, very gentle. I held this bird, he didn't know me at all, and I pet him, and he just looked at me. Not mean at all.
Should we separate the little black silkie from the other two? When she is separated from them, she calls out to them so I put her back in with them.
