We think this is a black Cochin. We thought "she" was a hen, but we've had the worst track record (out of the 5 "hens" we got last year they all turned out to be roosters except this one. the other ones were different breeds though and easier to distinguish). She does make kind of a "crowing" sound, and hasn't layed any eggs and she is almost a year old. Can you tell me? Hen or Rooster? Thanks!
