I have three 2 month old chicks. I bought my EE and BR chicks as pullets when they were a week old and I just got a straight run Polish/Silkie mutt yesterday. Since the beginning, the EE has been very aggresive. She would jump at the BR chick and bite. I had to separate them after a few days because the BR had a red mork on her beak due to bites from the EE. A few weeks later I put them together and the BR stood up for herself more so they got along fine. Now they are starting to fight again and the EE is also bullying my new polish/silkie mix. Is my EE the dominant hen trying to establish her dominance or is she just aggresive? I dont want the others to get hurt. I noticed a red spot on the polish/silkie's beak last night and I got her yesterday afternoon.
