Hello, I am new to the forum and new to Chickens. Yesterday I added what I believed to be two hens and a rooster to the flock. The 2 hens and rooster all came from the same pen at the place I bought them. When I got them home the rooster began pecking the light brahma to the point she buried her head in the corner and wouldn't look up. Today she wouldn't come out of the coop, she roosted all day. I started wondering if maybe the brahma was possibly a rooster? She or he is about 5 months old. Is this normal? Thank you in advance for the help.
