So May 1 I bought 5 pullets. They are approx 15 weeks now. I'm thinking this Light Brahma is a rooster. She has been very bossy. She is the largest chicken...even larger than the Jersey Giant. Last week I noticed her grabbing the back of the neck of the other hens. Today my husband saw her mounting another (he thinks). She pecked at my son's hand - we've never had a chicken do this. Is she a Rooster? Not sure what to do if she is. Keep him? Never intended to have a rooster...only hens but like the idea of baby chicks.
