I have one Barred Rock and two Americaunas. I am pretty sure the two are female but do not know about the barred rock since there is nobody to compare her to. I have thought she was a female the whole time but then she recently started making a lot of noise, not exactly crowing but the others never make any noise so I am concerned. Plus her comb grew a ton. They are 19 weeks old and no eggs yet so the easy way of telling has not yet presented itself. What do you think, is she a boy or girl?
