Well, one of mine has only laid two eggs in her life, and she THINKS she's a rooster. And with the way she goes after my other hens (ahem), she would have ended in a stew pot if she wasn't named after a friend of mine (who keeps asking how "her" chicken is doing). So I can see a lesbian chicken never having laid eggs... Anyone want a butch hen?
I'll take a butch hen! My roos might think to tell her what's what though... Do you have a roo? I've heard stories of a flock of all females and the top female doesn't lay, "mates" the other chickens and acts like a roo- sometimes to the extent of crowing.
I had a serama hen that laid me about 2 eggs in the year I had her. Nothing seemed to be wrong with her. I found her dead the other day though. I don't think she was very old, she just never laid for me.
