New here and new to chickens. I introduced myself in the other thread 
So I'm worried we might have some gender problems with the 3 barred rocks I got that were supposed to be all female. The two older ones are between 6-7 weeks and about to move outside today or tomorrow. However, I'm nervous they could be boys, but still think they are girls.
About 3 weeks ago we got 3 barred rock chicks around 3-4 weeks old from a local breeder. I'm inexperienced but after 2 weeks I could tell one was almost 100% rooster. He was lighter and bigger than the other two and his crown was already bigger and redder than the other two. He was more skittish as well. So we contacted the person and they gave us a new chicken. It is against more city code to own roosters.
I'm really concerned about the other two now because I don't want to get in trouble. My neighbors are peering at my new hen house and they aren't too fond that they found out I owned more land than they thought and built a fence around my property. I'm worried if one of them ends up crowing it will be trouble.
The little one is still a toss up, but looking at the two older ones, they're crowns are coming in earlier than I though (although not nearly as much as the boy), but they are darker, have some black on their feet. I'm hoping for good news. Sorry for the long post. I appreciate any help.
