We bought 4 pullets hens all around the same age but all different breeds; a barred rock, a golden spangled hamburg, a buff orpington, and a blue ameraucana. All the birds have been producing wonderfully except for the blue ameraucana. And more recently this fruitless bird has started to cock-a-doodle-doo like a rooster. Well, obviously we are beginning to wondering if she is really a hen. I tried to look up some pictures but the blue ameraucana roosters seem to look about the same as the hens. What is even stranger about this whole senario is that the ameraucana is at the bottom of the pecking order. I am puzzled. We live in a fairy dense neighborhood though and it is beginning to be a noise disturbance. Not to mention that it is illegal to have a rooster in city limits. Any thoughts or suggestions of how to curb this bird's behavior or tell if it is a hen or rooster?
