I am fairly new to the chicken game. I purchased some brown egg layers last year and have had great success. This spring, my wife purchased a batch of rare breed strait run birds with the intention of keeping the hens, and finding new homes for the roosters.They are 9 weeks, and so far, I cannot tell who is what. I'm enjoying watching the different breeds grow. I was just wondering at what age I will be able to determine who is a rooster, and who is a hen?

Thanks
