Hi, first time raising chicks. I have 6 chicks in one brooder, different breeds, all are about 2 weeks old. Today I noticed that one of my barred rocks and 1 EE were sparring. They had their wings spread out and were putting their beaks to each other. They are very feisty, and when riled up, try to fly around our brooder. All my chicks are supposed to be pullets. Is this normal pecking order behavior for females, or could this be early signs of rooster-ness?
