We have two Red Stars, both approx. 18 weeks old. I assumed they were hens since as chicks they were both red. But Carmel's comb is not only way bigger than the other Red Star but it's bigger than any of our other six chickens (all between 14 and 19 weeks old). Carmel is also definitely squawkier than the other chickens. So my first question is are Red Star roosters ever red instead of the normal white and buff color? But then I read where their crops grow larger when they start laying eggs. Could that be the explanation for the squakiness and the enlarged comb? Here's a picture: http://s1215.photobucket.com/albums/cc515/jonwross/?action=view¤t=IMG_0132.jpg (I'm unable to post pics here ... I'm still unclear about how that you gain that privilege). You can see the other Red Star in the background. Here's a closer pic of the other Red Star, just to give an idea of the difference. Is it common for them to develop at such different rates? http://s1215.photobucket.com/albums/cc515/jonwross/?action=view¤t=IMG_0134.jpg As always, I appreciate the feedback from all you awesomely helpful and knowledgable folks! Thanks!
