I have a rescue hen that I have quarantined for about 2 months now. She was in her own pen that was next to my 3 silkies (2 roasters and a hen). My rescue (Betty) is just so sweet. I tried to introduce her to my silkies. At first it was fine, 2 came over pecked a bit then went about their business. My less dominate rooster seemed mad, he went after her and then my other rooster joined in. It didn’t seem to pecking order procedure but a full on attack. Since I was there I just scooped betty up and put her back in her pen. I have tried a few more times over several days but this one rooster just seems to hate her. Any thoughts? I have tried vicks on her neck, pecking the rooster with my finger to show I am the leader but nothing seems to work. I don’t want to leave betty in by herself as she loves to be out in the main coop but I can’t bare to have her get hurt either.
