I am not sure I am in the right area to post this. I bought 4 little Araucana chickens. I wanted one rooster. She said she thought I had one rooster and 3 hens. How old do they have to be to know if I have a rooster? I am not sure how old they are but they seem to be almost full size now. The one she said is a rooster is the same buff color and has a small cone on its head. I just not sure if its a rooster or not. Is their any other way to tell before it starts to crow? I cant say it has spurs as don't they all have little ones anyway? Thanks for any help to this very new chicken owner.
