Hi It has been such a long time since I have owned chickens. I was just a kid then. I finally got some chicks. I was hoping to just have pullets, but I did get some straight run. So there is definitely possibility that I got some roos. I am on a 2 acre lot and we can keep chickens as long as our neighbors are okay. I don't want to have to deal with that if I don't need to. So my question is, at what age will roos start crowing? It always seemed like it was right before they were full grown. But I keep seeing here and there posts of as early as 3 weeks. Is that really possible?
