So we originally had 3 Ameraucana 'hens', but 1 of the 3 had always looked different - had a different (prettier) color, had a larger comb, had one very long tail feather that stuck out over the rest, and finally one day started crowing. I cant have a rooster where I live so he had to be rehomed. Well, a few days later we heard crowing again from the coop - and it was the other 2 Ameraucanas! They look much different from the rooster, so I went to Google and read about hens that crow in the absence on a rooster. We separated them and moved them into our garage temporarily, but now I honestly have no clue if they are hens or not.. they are now 5 months old. Any help is much appreciated as I am new to owning chickens, but I really wanted Ameraucanas for their colored eggs!
