I have 30 RIR hens 16 mths old. I bought them 1 day old and as soon as they were old enough, we butchered the roosters or gave them away. Yesterday I saw, what I thought was a hen, mounted atop of another hen. Just for a second, but she had ahold of the other hens neck and acted like she was a rooster. Now I have heard of hens crowing when there is an absence of roosters, but this? I looked her over good. She/he does not look like the roosters we got rid of. Could she be a he that looks like a hen? Could she just like girls? I have never gotten 30 eggs a day from these girls but have no way of seperating them out to see who is laying and who isn't. Someone plz tell me WHAT IS GOING ON?!
