I have a flock of 15 chickens. I have a mix of Rhode Island Reds and Buff Orphs. One of my Buffs really looks and acts like a rooster. Has the long neck feathers and the fanned out tail feathers and is noticeably larger then the rest. He/She holds the other buff hens down to "mate" with them and acts like a rooster puffing out chest and all. My concern is that I have never heard it crow. Is this normal for this breed? I did have 2 RIR roosters that crowed all the time but we have not heard this one crow. My husbands uncle told him that this was an "alpha hen" that portrayed a rooster to let the others know she was the boss. Anyone heard of this or had anything like this happen?
