I have (6) 18 week old chickens. One is most definitely a rooster, big beautiful boy with a crow that will pierce your ears. He is a BA (at least that is what we were told). We have another BA that is the same age as this boy, but looks much different and smaller. I assumed she was a hen, but "she" is crowing and her crow sounds exactly the same as her sibling! Same pattern, volume and tone. We also have 4 RIR that we were hoping were all hens. I have been hearing a crow from at least one of them that sounds a lot like our BA did when he first started crowing. Kind of raspy. It has a different tune, but definitely a crow. All 4 of these look almost exactly the same in coloring, feathering and size. Are the two "girls" that are crowing really not girls? I have read that some girls will crow in the absence of a rooster, but that isn't the case here, so I am really second guessing the sexes. Here is a picture from today of the to BAs (and 1 RIR to the left) to show the difference between the two. One of the RIRs from about a month ago: So, what's the verdict? Do I have any hens or are the all roos?
