This chicken is about 6 months old. No crowing yet. We had a mille fluer rooster that we traded for this barred rock (which looked very much like a hen at the time). The mille fleur was crowing at 3 months. When we brought the barred rock home it was about the same size as our now 6 month old buff. Now as you can see is significantly larger. What you you all think? If he is a roo, when do you think the crowing will begin?
