I learned it from my uncle , he raised tons of chickens. WhenI was younger , I spend more time with baby chickies, I learn something new about them , that was years ago. today have 9 older chickens and hoping to hatch some soon. I have an ameuracana , that I bought from someone else when they were about 5 weeks old, My daughter pick one she likes, and I told her I was afraid he will be a rooster (Looking at his eyes) sure enough I was right ! I had to find a home for him. one rooster is enough for me !! maybe I am a phychic!
