I know this thread is kinda old....but I've gotta add to it.
I have two hens, I've named them Ellen DeHenneres, and Dinah (something that sounds like Shore). They are a lesbian couple!! They have hen sex all day long. My rooster, RooPaul, runs over all upset and ready to fight when he sees someone mounting one of "his" girls. When Ellen hops off, RooPaul checks her up and down and realizes she is a hen not a rooster! He gets all confused but waddles off instead of cockfighting.
You may ask "gee, how can hens have lesbian chicken sex?" Apparently cocks don't have a cock, so all chicken sex is kinda the same...
