One of my Cochin hens thinks she is a roo!!! She tries to crow! She strains that neck and lets out the most pitiful crow like sound. She's been doing this for a year now. I don't know what her deal is. She lays eggs... does all that hen stuff. But then when the men sound off she joins in too. It is the most irritating sound. And it looks like it's painful to her. Anybody got any ideas?
