Hi Everyone! We're new with chickens and seems that one of our pullets might be a rooster. We added her when she was 3 days old to our three friendly 2-3 weeks old chicks. I was pretty worried she'd be in some sort of danger because of the age difference but it turned out to be vice versa. She quickly became the most aggressive and wildest little chicken. We thought maybe it's because she's much younger she feels like she needs to fight for her place under the sun and that she will get used to us and the flock eventually. Well she still is afraid of us and she still jumps and pecks at the other pullets quite often. I feel sorry for my other babies and don't know what to do. So is our Elsie still Elsie or Elvis at this point? Pretty determined to do DNA testing but thought I should ask the real experts first. Thank you, guys!
